You are saying that some member of struct thread_state, probably
m_getcjmp, has a 16-byte alignment, at least in the 64-bit Windows
build.  GCC sees that, and therefore deduces that the entire struct
must be 16-byte aligned, so it feels free to emit movaps in
conjunction with the m_stack_bottom member, which is at offset 64
(decimal) from the struct base, and therefore should also be 16-byte
aligned.  Is that correct?
