Bug 1063089

Hello,
 Could you specify which version of XBMC you tried to compile, and from where you obtained it? Also what is the specific error that you see and at which stage of the compilation (do you see it on configure time, or compilation time?).

config.log

Thank you for your quick reply!

It happens with both XBMC 13.0 Alpha 10 and Alpha 11.  I am seeing the error during configure.  Attached is the config.log.  I was able to compile the source rpm yesterday morning before doing an update on my virtual machine.  The last update I had done was a week ago.  After the update, the configure script failed on the segfault shown in the config.log.  I made a list of packages upgraded by yum update that were listed in the gdb backtrace given by XBMC and downgraded each in turn until I found the one that caused the error.

When running XBMC, there is a crash upon exit.  XBMC creates a crash log upon exit and then restarts itself instead of exiting to the shell.  This happens on my virtual machine running Fedora 20 with all updates and my working machine, also with all updates.

I have tried with the 3.12-8 kernel as well and the same things happen.

I hope this is more clear now.

I'm sorry, I neglected to mention the source.  I got the source rpm from RPMFusion.

http://download1.rpmfusion.org/free/fedora/releases/20/Everything/x86_64/os/xbmc-13.0-0.2.Gotham_alpha9.fc20.x86_64.rpm

I changed the rpm to download the Alpha 11 version of XBMC.  This also happens with the unchanged rpm.  I just tried it again to be sure.

The error is a segfault in the configure script as I said in my last comment.

How did you correlated this issue with "gnutls.x86_64 0:3.1.20-1.fc20"? It seems that on of the configure scripts crashes while testing the compiler. I believe that this bug should be assigned to xbmc, and if there is some issue in gnutls found out, please follow up.

btw. You could get more information about the crash by installing the debugging symbols (of gnutls and xbmc) and run valgrind on the executable.

valgrind on xbmc.bin #1

I did get xbmc to compile by removing the reference to the mysql library and
the hdhomerun in the spec file.  Unfortunately, it still crashes upon exit.  I'm
trying to track down the cause on the xbmc forum, with the devs doing the suggestions.

I did as you said and ran valgrind against the xbmc executable.  I don't know much about valgrind and used this command line that I found on an introductory page:

valgrind --tool=memcheck --leak-check=yes --show-reachable=yes --num-callers=20 --track-fds=yes /usr/lib64/xbmc/xbmc.bin > valgrind.txt 2>&1

That generated a lot of text on the crash.  I did a grep on gnutls and only found the point where it initialized.  There may be more information there.  I have attached the log.

If you have a command line that would be more effective, I'll try that as well.

Thanks,
Jerry

The valgrind log doesn't show anything suspicious on gnutls (except a small memory leak). Most probably the change in gnutls version (and size) has uncovered an unrelated bug in xbmc. I'll close the bug, but feel free to re-open if more information is available and I'm proven wrong.

Hi Nikos,

The xbmc guys had me run a gdb backtrace and they think it's crashing in a system library somewhere.  Here is the link to the backtrace: http://xbmclogs.com/show.php?id=131393

I'm not sure if that sheds any light on the situation.  I installed nearly 4 GB of debug information!

Does that make any more sense or is the situation still unclear?

There is no crash in the log that you sent. The interruptions are due to thread creation.

Here is a crash in zabbix which seems to be related to a gnutls upgrade:

See also https://bugzilla.redhat.com/show_bug.cgi?id=1069079 for a trivial reproduction case unrelated to RPM Fusion packages.

Thanks. It seems there is an issue in libtspi. I've re-assigned the bug accordingly.
