------- Additional Comments From bangerth at dealii dot org 2004-10-15 18:40 ------- I have a very similar problem in my program. It segfaults in this instruction: 0x0815935d <vector+203>: movapd %xmm0,(%eax) where I have eax 0xbfffd874 -1073751948 and (gdb) p ((unsigned int)0xbfffd874) $1 = 3221215348 (gdb) p ((unsigned int)0xbfffd874) % 16 $2 = 4 So indeed movapd isn't writing to 16-byte aligned storage.
