Here is the reduced sources (might be fixed on the mainline):
typedef struct {
int i;
int j;
int k;
int l;
} mach_msg_header_t;
struct mach_trap_args {
void *rmsg;
};
typedef struct {
mach_msg_header_t rep_msgh;
} mach_vm_wire_reply_t;
int
mach_vm_wire(args)
struct mach_trap_args *args;
{
mach_vm_wire_reply_t *rep = args->rmsg;
__builtin_memset((&rep), 0, (sizeof(*rep)));
return mach_msg_error(args, 22);
}

__builtin_memset((&rep), 0, (sizeof(*rep)));
is of course invalid code.

__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.

Simplified testcase. This bug is probably a WONTFIX.
int bar (int *);
int foo (void)
{
int x;
__builtin_memset (&x, 0, 32);
return bar (&x);
}
