I'm not sure where the initial problem is, but by the time we've got down to
machine level we get this:
0x425f74: movdqa 0x231454(%rip),%xmm0 # 0x6573d0
0x425f7c: movdqa %xmm0,0x231454(%rip) # 0x6573d8
Which is clearly not ok. For a start, long2 isn't 8 bytes wide. The segfault is
probably a GP from the ensuing misaligned store.
