debug logs for openblas git e01b3d4b546d8
built with make USE_THREAD=0 NO_LAPACK=1 DEBUG=1
which resulted in the barcelona target

the interesting parts are input 221 which loads the two element vector
and a nan following it into xmm5
the nan is probably a remnant from the previous run

2: $xmm2.v4_float = {2, 1, -nan(0x7fffff), 2.06249976}

which then spreads to the result during the hadds beginning in input 420
it also happens with only SSE2, only disabling sse completely fixes the
issue
