llvm-gcc miscompiles this at -m64, not properly aligning the "1":
struct ty {
int info;
union {
int id;
char *str;
} u;
};
struct ty vals = { 101, 1 };
$ llvm-gcc t4.c -S -o - -m64
_vals: ## vals
.long 101 ## 0x65
.long 1 ## 0x1
.space 4
.space 4
$ gcc t4.c -S -o - -m64
_vals:
.long 101
.space 4
.long 1
.space 4
