So it looks like new_thread could be aligned at just 8 bytes, but GCC assumes for some reason that it's 16-byte aligned, and issues an instruction that requires such an alignment.
It's not a GCC bug. It's a bug in the way that Emacs allocates pseudovectors. We assume that an alignment of 8 is enough, but apparently this is incorrect for the struct thread type under MS-Windows. I'll see if I can squeeze some time free to look into this.
