MPlayer interrupted by signal 11 in module: decode_audio

  • MPlayer crashed by bad usage of CPU/FPU/RAM. Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
  • 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/HTML/en/bugreports.html and follow the instructions there. We can't and won't help unless you provide this information when reporting a possible bug

Program received signal SIGSEGV, Segmentation fault.

  • Priority changed from important to if idle

In mp3lib (imported library) -> reduce priority.
I will mention this only once: I'd like to see all these reports fixed, but there are too many and too few working on them, so I will move all invalid reads and memleaks in imported libs to lowest priority (since they are difficult to fix for me, there is often an alternative in FFmpeg and upstream might fix them).

Note: See TracTickets for help on using tickets.
