Another simple testcase:
---
static char buf;
void
test6 (void)
{
int len;
void *p;
for (len = 0; len < 2; len++)
{
p = __builtin___memset_chk (&buf, '\0', len, 1);
if (p != &buf) return;
}
}
---
fold_builtin_memset was added to return COMPOUND_EXPR via
omit_one_operand. But there was nothing added to handle it.
