The return from foo() with -flate-combine-instructions has one bit difference:

$2 = {0xffffffffffffffff7fffffff7fffffff, 0xffffffffffffffffffffffffffffffff,
0xffffffffffffffffffffffffffffffff, 0xffffffffffffffffffffffffffffffff}

vs. (correct) compiled with -fno-late-combine-instructions:

$2 = {0xffffffffffffffffffffffff7fffffff, 0xffffffffffffffffffffffffffffffff,
0xffffffffffffffffffffffffffffffff, 0xffffffffffffffffffffffffffffffff}
