Thanks for your suggestion.
I upgraded glibc to 2.3.5-r1, as you suggested, but the problem still
persists.
While I'm not a programmer, this error sounds like incorrect memory
allocation by mplex.
If this is a bug, to whom should I report it?
Has anyone else experienced this problem?

Hello,
I'm running Gentoo Linux with a 2.6.9 kernel; had transcode 1.6.2-r4
installed.
I just upgraded glibc to version 2.3.5, and suddenly mplex stopped
working in a distinctly unfriendly fashion.
`mplex -f 8 -o foo.mpg foo.m2v foo.mp2` yielded one of these:
*** glibc detected *** double free or corruption (!prev): 0x800081c8 ***
What's particularly bothersome about this is that mplex performs just
fine
on several other files:
`mplex -f 8 -o bar.mpg bar.m2v bar.mp2`
I should mention that I compiled glibc, and subsquently mjpegtools,
with a
hardened gcc profile (SSP & PIE). I'm concerned that might be the
source
of the problem. So I recompiled mjpegtools with a vanilla gcc profile -
again, to no avail; mplex still keeps throwing that nasty glibc error.
Can anyone tell me how to proceed with troubleshooting this, short of
downgrading glibc?
Thanks,
cs
Hi,
From Gentoo's sys-libs/glibc/ChangeLog :
16 Aug 2005; Jeremy Huddleston <[EMAIL PROTECTED]>
glibc-2.3.5-r1.ebuild:
Stable on amd64 and x86 to address issues which cropped up since 2.3.5
went
stable. This fixes bugs #52374, #85718, #100190.
At least one of the bug reports uses hardened gcc.
So if you're still running 2.3.5, maybe an update to 2.3.5-r1 could
help.
