Description
Various values of $CPU crashes or generates incorrect results for make fate-h264-reinit-small_420_8-to-large_444_10 CPUFLAGS=$CPU
$CPU=sse/mmx/mmxext/sse4.2 passes
$CPU=sse2/ssse3 crashes
fault in ff_hscale8to15_X8_sse2
pmaddwd (%r10,%rax,2),%xmm1
p/x $rax = 0x1
p/x $r10+2*$rax : 0x8ba8b42
can't pmaddwd from an unaligned address
$CPU=sse4 doesn't crash but fails

he did:
make fate-h264-reinit-small_420_8-to-large_444_10 CPUFLAGS=sse2
Crashes here as well.
The fact that the other cpu flags don't crash is most likely because there are no optimizations outside of sse2 and ssse3 (and selecting sse4.2 does NOT enable any previous optimizations, for exmaple)

Shouldn't this be "CPUFLAGS=mmx+mmxext+sse+sse2" (or whatever the exact syntax is)?

Could you post a command line that allows to reproduce the crash?
