[MPlayer-users] Bugreport: -ao pcm segfaults

[Michael Lehmeier]

Simple pcm audio output into a wav file crashes at the end with SIGSEGV.
This leaves the wav file unusable for mp2enc.
This seems to affect every mpeg file (1 or 2) I have.
This bug is new in rc3, MPlayer-0.90rc2 worked and works perfectly.
