Confirmed, here is a testcase which uses abort:
typedef float V __attribute__ ((vector_size (16)));
typedef __SIZE_TYPE__ uintptr_t;
V foo;
void abort (void);
int main(void)
{
V *foo2 = &foo;
if (!(((((uintptr_t)(((float *) (((uintptr_t) foo2) & ~(uintptr_t)3)))) % 8) == 0) && !(((uintptr_t)foo2) & 1)))
abort ();
return 0;
}
