Subject: Oops with alsa (oss emulation)

Hi

when i run
mplayer -speed 3 movie.avi
mplayer segfaults and there is an oops in the logs

The above command line plays the movie at a speed above normal. It happens
for any value of speed > 1.

It's 100% reproductible. It oopses with any media file (an mp3 file for
example), and with kernel 2.6.4 and 2.6.5rc2.
Kernels 2.6.2 and 2.6.3 work fine.

Dmesg, program version and config attached

Bye
Calin

I cannot reproduce here - gcc 3.3.1 (SuSE), 2.6.4. It seems that you
trigger the gcc bug. Try enable CONFIG_FRAME_POINTER in your kernel and
let me know, if it helps.

Yes. If i enable CONFIG_FRAME_POINTER in my kernel works ok.
I'll upgrade my gcc.

Thanks for help
