• 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.
