Comment(by awithers):

 (In [13796]) References #3634

 Force float array to align(16) for call to ff_imdct_calc_sse.
 The ff_imdct_calc_sse function uses movaps which will cause a GPF
 on unaligned data.

 Another solution would be to have ff_imdct_calc_sse use movups. I'm
 only using the align fix as assuming correct alignment seems to be
 common elsewhere in there.

 There may be problems with align for some versions of gcc.
