        __builtin_memset((&rep), 0, (sizeof(*rep)));
Is overriding the slot for the link register so gcc is trying to remove the instruction that 
stores the link register on the stack so gcc ICEs.

The reason why this ICE on netbsd and linux and not Darwin and AIX is because the ABI 
is different as Darwin uses the AIX stack frame while netbsd and linux uses the SYSV 
one.
