[xine-devel] SIGSEGV while playing MOV file

[Chris R. <ran...@ya...>]

Hi,

xine has started to SIGSEGV whenever I try to play certain MOV files. This is the backtrace:

(gdb) where
#0  0xb6505087 in ?? () from /usr/lib/i686/libavcodec.so.52
#1  0xb652d76a in ?? () from /usr/lib/i686/libavcodec.so.52

#6  0x4407b935 in start_thread () from /lib/libpthread.so.0
#7  0x43fb094e in clone () from /lib/libc.so.6

This is using xine-lib 1.1.16.3hg from the repository, linked against the ffmpeg packages from Fedora 11:

ffmpeg-devel-0.5-3.fc11.i586
ffmpeg-libs-0.5-3.fc11.i586

I have a fragment of a MOV file that reproduces the problem (100K) that I can send to anyone who is interested. The end of the verbose log looks like this:
