okay, I just put USFs in my playlist again for the first time in months, in the interests of producing a reproduceable crash. My playlist is about 15,000 songs, and whenever there's USFs in there, a crash is inevitable.
My first crash is:
Unknown x86 Opcode
location D46FFDF
loc 987FFDF
fhfgh2
This was caused when Winamp shifted from a Chrono Cross PSF (Lost Fragments) to a Perfect Dark (Combat Simulator Menu) USF. I got that dialog, and then Winamp promptly crashed. I was able to reproduce the crash by loading in the PSF and the USF into the playlist (2 songs only), and setting it to shuffle, and repeat. I pressed the next track button until Winamp crashed once more. (It took about 20 clicks).
My system configuration:
Athlon 64 3500+
1GB PC3200 Dual Channel
Windows XP Pro (32 bit)
My Winamp configuration:
