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 GNU C Library stable release version 2.3.4 (20050218), by Roland McGrath et al.
