Btw, is memory alignment ensured somwhere by use of posix_memalign() to
do all allocations which are touched by for example SSE functions?
Typical problems are use of malloc() in combination with "movaps"-style
instrunctions.
Regarding ARM, at least some ARM versions have been pretty braindead
regarding non-32-bit-aligned memory accesses. (this has hit me in the
past with crypto and video codec stuff)
