Register Allocation ERROR! Ran out of registers during register allocation!

Hi all,
My Machine environment is Clang-2.8-svn on Linux-x86. When I build ffmpeg-0.6 using Clang, error output:

CC libavcodec/x86/mpegvideo_mmx.o
fatal error: error in backend: Ran out of registers during register allocation!
Please check your inline asm statement for invalid constraints:

Fast register allocator and Linear scan get the same error.
