Confirmed, a reduced testcase:
void tree_insert();
int empty, nulls;
char found;
long long min_arg, max_arg;
static inline int compare_longlong(const long long s, const long long t) {
return ((s < t) ? -1 : s > t ? 1 : 0);
}
int num1();
int null_value;
void add(int room_in_tree)
{
long long num = num1();
if (null_value)
{
nulls++;
return;
}
if (num == 0)
empty++;
if (room_in_tree)
tree_insert();
if (!found)
found = 1;
else if (num != 0)
{
if (compare_longlong(num, min_arg) < 0)
min_arg = num;
if (compare_longlong(num, max_arg) > 0)
max_arg = num;
}
}
----
This one fails at -O2.
This also might fail on the mainline with -O2 -fno-tree-vrp.
Also this one might fail in 3.4.x also but I have not tested it there or on the
mainline yet.
