Yes, this one is real crash, whereas I had assertion failuer (in case of
the tt.py script I sent lastly). This looks as if vectorization weren't
disabled, though:

emmintrin.h is sse2-specific header (judging by comments at the
beginning of that file), and it shouldn't be used at all if you disable
vectorization.

Sorry, I don't have the answer here and I wish you good luck finding the
problem. I might try monday, I have to write an exam paper deadlines
sunday evening.
