[MPlayer-users] BUG: mplayer cvs received SIGABRT

[Svante Signell]

Recent mplayer from CVS (2004-06-09,2004-06-28) fails to play files with
6-channel or mp3 audio with -ao alsa and alsa modules loaded. With -ao
oss all is OK. mplayer cvs from 2004-05-12 with -ao alsa1x is OK too.

(I'm currently compiling CVS from today with debug flags set.)
Adiocard is a Creative SB AWE64 (snd-sbawe):

Same mplayer version works on another box with an SB live! card
(snd-emu10k1).

MPlayer interrupted by signal 6 in module: play_audio
- 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.

gdb trace ouptut:
