Extended Description

Hi all.

This program makes clang-trunk crash under O2~Os options.

$cat small.c

#include <stdint.h>
void a() {
uint64_t *b;
uint64_t *c;
uint32_t d;
uint64_t *e;
if (*c) {
for (; e <= 7; e++) {
int64_t f = 0;
c = f;
}
if (*e /= e <= c) {
uint64_t g;
for (d = 7; d;) {
uint32_t *j = &d;
i:
(*j = g) != (*c ?: d ?: *b == 0);
if (d = c > 0)
g = 0;
}
}
for (; d;)
;
}
goto i;
}

$clang -c -w -O2 small.c

Hi. This crash can not be reproduced on the current trunk of clang. Can I just close it as fixed? Thanks.
