[mpeg2-dev] Crashes in sse2_idct x86_64

[John S. <ste...@je...>]

Have there been any new developments on this problem?

I am seeing similar (if not identical) behavior from libmpeg2 compiled with the mingw64 cross tools for fedora 
(available here http://build1.openftd.org/mingw-w64/)
After disabling gcc optimizations and enabling debug, gdb indicates the crash happens in sse2_idct at the first movdqa_m2r.

There are also reports of similar crashes in sse2_idct due to recent gcc 4.6 changes.

The patches in this thread fix the problem on fedora 15 where this is reproducible, but not for mingw64 builds 
unfortunately.
