[MPlayer-users] argument parsing bug

[benoit bourdin]

Hello guys,

bug reported: 
argument parsing seg faults in the case of :

bennyben at masterbenny:~/softs/MPlayer-20020508$ ./mplayer -sdl:aalib


MPlayer CVS-020508-06:00-2.95.4 (C) 2000-2002 Arpad Gereoffy (see DOCS!)

CPU vendor name: GenuineIntel  max cpuid level: 2
CPU: Intel Celeron Covington/Pentium II Deschutes,Tonga/Pentium II Xeon (Type: 6, Stepping: 2)
CPUflags: Type: 6 MMX: 1 MMX2: 0 3DNow: 0 3DNow2: 0 SSE: 0 SSE2: 0
Compiled for x86 CPU with features: MMX
Segmentation fault (core dumped)

(but works well using the correct syntax: -vo aa, and -vo sdl)

If I recompile mplayer with --enable-debug=3 option to configure :

Core was generated by `mplayer -vm -sdl:aalib'.
Program terminated with signal 11, Segmentation fault.
#0  0x0806a8ea in play_tree_prepend_entry (pt=0x0, entry=0x0) at playtree.c:103
103       for(iter = pt ; iter->prev != NULL; iter = iter->prev)


It should be a piece of cake now :)
Good luck, you've done a good job.

Bye
