[MPlayer-advusers] [BUG] mplayer -vf spp segfault on pentium 4 with gcc-4.0

[Corey Hickey]

I ran accross this while testing a video on my laptop for the Doom9
codec comparison.

The following command immediately crashes mplayer compiled with gcc-4.0:
$ mplayer some_file.avi -vf spp

amd64,    gcc-4.0 : works fine
pentium4, gcc-4.0 : segfaults
pentium4, gcc-3.4 : works fine

The crash seems to happen with any file, but if you want the file I used
for the attached gdb log, it's at:
