Description of problem:
Lame segfaults with kernel-18.104.22.168_2080_FC5.i686
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Find a WAV file (let's say its name is test.wav).
2. Run lame as follows: "lame -b 160 test.wav test.mp3"
3. The lame program quits with the "segmentation fault".
Lame encodes test.wav into test.mp3 at 160 kbps bitrate.
Tried the exact same process with 2.6.15-1.2059_FC5.i686. Unable to repro.
Indicates that the kernel 2.6.16-1.2080_FC5 is the culprit (AFAIK).
after the segfault happens, is there anything in dmesg ? a kernel oops perhaps?
Thanks for the prompt response. I checked the output from dmesg. Unfortunately,
it does not include anything relevant to the crash.
I took the source RPM of lame 3.96 and rebuilt it with kernel 2.6.16-1.2080. It
did not get rid of the problem. Just FYI...
One more thing to report. I rebuilt lame using the latest (3.97b2) source. The
segfault problem does not manifest itself anymore. Without debugging lame itself
I am not sure where the real culprit is, but I thought I'd let you know anyway.
I have the same problem with lame-3.96.1-2.2.fc4 (freshrpms) on FC4 with
If I boot with kernel-2.6.15-1.1833_FC4 lame works fine!
How about try "lame --noasm xxx.wav", some Athlon CPU need this to solve this
problem(avoid using 3dnow)!
The man page ("man lame") does mention the "--noasm" flag, but it says it is for
Cyrix/Via CPUs, not AMD. Besides, lame 3.96 was working fine without that option
with kernel 2.6.15.
I could go back to lame 3.96 and try it, but I'd rather not touch the currently
working configuration (2.6.16-1_2080 and lame 3.97b).
A new kernel update has been released (Version: 2.6.18-1.2200.fc5)
based upon a new upstream kernel release.
Please retest against this new kernel, as a large number of patches
go into each upstream release, possibly including changes that
may address this problem.

In the last few updates, some users upgrading from FC4->FC5
have reported that installing a kernel update has left their
systems unbootable. If you have been affected by this problem
please check you only have one version of device-mapper & lvm2
installed. See bug 207474 for further details.
