[MPlayer-users] MPlayer crash related to caching

[andrew]

Hi,

I am having a reproducible crash with:

andrew at skamandros:~$ mplayer | head -4
MPlayer dev-SVN-r26915-4.2.3 (C) 2000-2008 MPlayer Team
CPU: Intel(R) Core(TM)2 CPU         T5500  @ 1.66GHz (Family: 6, Model: 15, Stepping: 2)
CPUflags:  MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1
Compiled for x86 CPU with extensions: MMX MMX2 SSE SSE2

The crash appears to relate to caching and occurs while playing a
streaming Real Audio file as follows:

MPlayer interrupted by signal 11 in module: enable_cache
- 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.
Cache fill:  2.50% (8192 bytes)
v+-------------------------------------------------

I was unable to reproduce the crash with gdb as MPlayer
would hang indefinitely on "Cache fill:  2.50% (8192 bytes)" _below_ the
actual error message but I found that I could avoid the crash
completely by eliminating caching with the following syntax:

andrew at skamandros:~$ mplayer -nocache -playlist
http://www.abc.net.au/classic/ftgws/audio/ftgws_25052008.ram

Please tell me if more information is required.

          Andrew
