The original problem was fixed in 4.5.

The issue with global MMX registers (Comment #3) won't be fixed - it is user
error, please see Comment #5 for the explanation. Also, according to MMX ABI,
it is user responsibility to call _mm_empty at the end of MMX intrinsics
sequence to "empty the multimedia state".

The problem from Comment #7 is fixed in 4.7.4, 4.8.1 and 4.9.0.
