<pre>Thanks for letting me reproduce this on ogopogo. It seems to be crashing at
this instruction:
0x00007ffff41106d9 <+169>: movaps %xmm0,-0x130(%rbp)
=> 0x00007ffff41106e0 <+176>: pand (%rbx),%xmm0
0x00007ffff41106e4 <+180>: movaps %xmm0,-0x120(%rbp)
GCC 5.4 seems to be vectorizing the 128-bit bitmask operation, but the memory
address of "this" is not 128-bit aligned (it's 0x7fffe8bff728 during this run),
which causes the crash. Probably a GCC bug...</pre>
