I can still reproduce this with today's mainline. The segfault still
happens in a movapd instruction:
0x08048389 <_Z1fv+21>: movapd %xmm0,(%eax)
(gdb) info registers eax
eax 0xbfffe944 -1073747644
This address is not divisible by 16. I am unsure whether this has something
to do with the stack alignment that always comes up -- here's my glibc
version:
home/bangerth> /lib/libc.so.6
