mplayer crashes when it tries to play VP6 compressed movie

[selmi@…]

file plays correctly using
mplayer -vc vp6 fmv12_generichub_english_ntsc.avi

but crashes using
mplayer -vc ffvp6 fmv12_generichub_english_ntsc.avi

unfortunately the second possibility is default, so it crashes unless you play with options

i used windows port of mplayer and i don't know how to build it there from sources, so i can't do better error report. but sample file is uploaded to upload.mplayerhq.hu, its name is vp6_crash.avi and description vp6_crash.txt

here is error message:

• MPlayer crashed by bad usage of CPU/FPU/RAM. Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
• MPlayer crashed. This shouldn't happen. It can be a bug in the MPlayer code _or_ in your drivers _or_ in your gcc version. If you think it's MPlayer's fault, please read DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and won't help unless you provide this information when reporting a possible bug.

btw i know its SVN revision is old, unfortunately from site there is only rc1 available for windows which is even older.... so i can't test if it now works better of not... if you will find file playable then sorry

File plays fine here. Related projects page has much newer Windows builds.

i tried it with almost current build, MPlayer Sherpya-SVN-r25088-4.2.1
and it crashes too... :-( so maybe its something fixed only short time ago or something related to builds from ​http://oss.netfarm.it/mplayer-win32.php (i tried both athlon and p4 build) or its problem in my system....
