[MPlayer-dev-eng] [BUG] mp3 decode crash

[Joey Parrish]

Hello,

While decoding mp3s, MPlayer crashed. My MPlayer source is
updated to the latest CVS (20 May 2002) and it still crashes.
Attached below is the verbose output of MPlayer and a gdb backtrace.
The file that caused this crash can be found at

Thanks.
