The alignas in NEWPOLY_POLY told the compiler that it could assume a
certain alignment. However, values were allocated with malloc with no
specific alignment.
We could try and allocate aligned memory but the alignment doesn't have
a performance impact (on x86-64) so this is the simpler change. (Also,
Windows doesn't have |posix_memalign|. The cloest thing is
_alligned_alloc but then one has to use a special free function.)
