It is a regression for PR 32893, which was fixed by disabling vectorizer on local variables requiring > 4byte alignment since we couldn't realign the stack at the time to support 4byte incoming stack. With automatic stack alignment, this restricting was removed. But since we assume incoming stack is 16byte, we don't realign the stack. When incoming stack is 4 byte aligned, we get segfault. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41156
