Comment 2 Brendan Jones 2011-04-04 08:53:25 EDT
I am also experiencing this on 1.9.7 on x86_64 - would provide a backtrace but GDB errors at the moment as well. Without looking too much into it, I rebuilt it locally without firewire and freebob and it started okay

Hi Brendan, Did you configure your jack as described in /usr/share/doc/jack-audio-connection-kit-VERSION/README.Fedora ?

Comment 9 Orcan Ogetbil 2011-04-04 22:22:29 EDT
hmm, how about the jackuser group? Are you a member of it? Also, did you try uninstalling pulseaudio? Do you get the same crashes without pulseaudio?
Comment 10 Orcan Ogetbil 2011-04-04 22:27:30 EDT
oops, I realized that what I said doesn't make sense. You already answered these questions. At this point, since I am not a jack developer, the best thing I can suggest is to file a bug to jack2 http://trac.jackaudio.org/ Please post here the link if you file a ticket, so we can track the progress and update/patch our packages if necessary.
Comment 11 Brendan Jones 2011-04-04 22:42:02 EDT
No problem. However, the problem looks to be occurring in libffado . I'll do some more debugging before filing upstream.
Comment 12 Brendan Jones 2011-04-05 18:10:59 EDT
I've reported this upstream here: http://subversion.ffado.org/ticket/329 A brute force workaround is to move /usr/lib64/jack/jack_firewire.so so it won't be loaded at runtime. Obviously this will disable firewire support
Comment 13 Mark van Rossum 2011-04-06 04:40:52 EDT
I experience this bug on a 32 bit system. I might have a special case as I have disabled firewire in my bios (I never use it). Brendan's fix works for me as well. Simply deleting /usr/lib/jack/jack_firewire.so solves it.

Comment 15 Brendan Jones 2011-04-14 09:44:33 EDT
One of the upstream libffado developers believes there maybe an issue with binutils, specifically in the final linking stage. The full text of the comment can be found here: http://subversion.ffado.org/ticket/329#comment:17 I am reassigning to binutils for comment..
Comment 16 Nick Clifton 2011-04-14 11:09:30 EDT
Hi Brendan, This certainly sounds like a linker problem, although I guess that there is a small possibility that it is actually a loader problem. Without more information as to exactly what is going wrong it is hard to say any more. But here are a few things that you could try: * If you build a linker from the current HEAD of the mainline FSF binutils sources and then link using that, does the problem persist ? * What about if you use the GOLD linker rather than LD ? (Configure with --enable-gold to get the gold linker). * How do the working libffado and the broken libffado differ ? (Running readelf -a on the two binaries is probably the best way to compare them, although that will produce a lot of output. Using readelf -e will produce a much shorter output). How does the broken version of libffado fail ? Is it another memory corruption problem or something else ? Cheers Nick

Created attachment 492382 [details] Disable initfini_array support.
Comment 21 Nick Clifton 2011-04-15 10:00:35 EDT
Hi Brendan, It looks like a problem with the linker's support for .init_array and .fini_array sections. Are you able to build and install a local binutils rpm ? If so, please could you try downloading the binutils source rpm, applying the uploaded patch to the binutils.spec file and then creating a test linker with which you can link jackd. if this works then it confirms the cause the problem, but not the actual nitty gritty of what is wrong. For that I will need to look at the libffado.so files built by the Debian linker and the (unpatched) Fedora linker. Cheers Nick
Comment 22 Brendan Jones 2011-04-15 17:41:31 EDT
No problem. I rebuilt binutils based on the spec in F15 with disabled initfini-array flag. Your patch was done on the version in rawhide I think. Linking with this version's ld was successful. The binary is here http://bsjones.fedorapeople.org/libffado.so.2.999.0-binutils-disable-initfini-array.tar.gz And the rebuilt binutils http://bsjones.fedorapeople.org/binutils-184.108.40.206.6-2.fc15.x86_64.rpm http://bsjones.fedorapeople.org/binutils-220.127.116.11.6-2.fc15.src.rpm http://bsjones.fedorapeople.org/binutils-debuginfo-18.104.22.168.6-2.fc15.x86_64.rpm
Comment 23 Nick Clifton 2011-04-16 04:04:41 EDT
Hi Brendan, > The binary is here Thanks for that. Can you also make a broken binary for me, so that I can compare the two and find out exactly which constructors/destructors are being called in the wrong order. Cheers Nick
Comment 24 Brendan Jones 2011-04-16 09:27:28 EDT

Comment 25 Nick Clifton 2011-04-18 05:59:32 EDT
Hi Brendan, Thanks for the binaries. Unfortunately I am baffled. The ordering of the constructor functions in the .init_array section of the enabled binary is exactly the same as the order in the .ctors section of the disabled binary. Plus there are no extra constructors in either binary. So in theory they should exhibit exactly the same behaviour. (There are no destructors in either binary). > The error is free() invalid pointer upon delete Can you find out any more about this error please ? For example, which function is executing the free() and from where should the corresponding malloc() have been called ? I am beginning to wonder if this is a loader problem rather than a linker problem. Maybe the loader is not executing the .init_array section properly. (This seems rather unlikely as surely lots of binaries would break if this were true). Cheers Nick
Comment 26 Brendan Jones 2011-04-18 06:19:07 EDT
Created attachment 492846 [details] debugmodule.cpp
Comment 29 Brendan Jones 2011-04-18 06:31:14 EDT
The error occurs when DebugModuleManager::~DebugModuleManager is called from ffado.cpp . It contains a vector of DebugModules which are iterated through - a delete on the dereferenced vector produces the crash. It is pretty easy to reproduce - install jack-audio-connection-kit, it will pull in libffado. Calling /usr/bin/jackd without any parameters will reproduce the crash. The upstream thread may provide some clues. The binaries the maintained used to debug this problem are there also.

Comment 31 Nick Clifton 2011-04-19 08:04:57 EDT
Hi Brendan, I am still struggling^H^H^H^H^H investigating this. One quick question - in DebugModuleManager::~DebugModuleManager() wouldn't it make more sense to walk the m_debugModules vector backwards ? Ie treating the vector as a stack rather than a queue ? (I assume that you will tell me that the modules are meant to be independent of each other and so the order of their deletion is irrelevant, but can this be guaranteed ?) As an aside I tried compiling the ctor_test.cpp app from: http://subversion.ffado.org/ticket/329#comment:19 and it works with and without using init_array sections. Cheers Nick
Comment 32 Brendan Jones 2011-04-19 09:21:51 EDT
Thanks for looking into this Nick. Some of these questions may be better directed to the developers upstream (I'm not involved in the ffado project). In the upstream comments a number of different methods of dealing with the vector were tried. Given that this is pretty important to the audio SIG wrt F15, do you have any suggestions for a possible work around (e.g. patching the libffado spec to use the goldlinker / or simply removing the call to ~DebugModuleManager?) Let me know if there is anything I can do. Brendan
Comment 33 Nick Clifton 2011-04-19 10:47:10 EDT
Hi Brendan, Using GOLD is definitely the easiest and best workaround for now. (It also has the advantage that GOLD should be faster than LD). I'll continue to look into this in the background, but at the moment I am stumped as to why putting the constructors into the .init_array section is breaking libffado. Cheers Nick

Hmm, not that I really know anything about the subject, but http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46770#c1 suggests that .init_array and .ctors are processed in opposite order: "Using .init_array/.fini_array instead of .ctors/.dtors removes the need for the associated (relative) relocations, and avoids the backwards disk seeks on startup (since while .ctors are processed backwards, .init_array is processed forward)" So if the ordering is the same, but they are processed differently, this would explain differences, wouldn't it?
