[MPlayer-users] Bugreport - mp3lib segfaults

Tue May 14 15:29:01 CEST 2002
This problem appeared in the CVS tree at some time between Sunday
morning and yesterday night. Whenever I try to read a file using the
mp3lib codec, it segfaults. This happens with both mplayer and
mencoder. Everything works normally if I use -afm 11, or -nosound.

MPlayer interrupted by signal 11 in module: init_audio_codec
- MPlayer crashed by bad usage of CPU/FPU/RAM. Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and disassembly. For details, see DOCS/bugreports.html section 5.b.
- MPlayer crashed. This shouldn't happen. It can be a bug in the MPlayer code _or_ in your drivers _or_ in your gcc version. If you think it's MPlayer's fault, please read DOCS/bugreports.html and follow instructions there. We can't and won't help unless you provide these informations when reporting a possible bug.
