--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The C++ testcase that is:
```
int a, b;
void c() {}
[[gnu::noipa]]
void h() {__builtin_abort();}
int d() {
unsigned f[1];
int i;
if (a)
goto h;
f[0] = -1;
while (1) {
c();
for (; a < 1; a++) {
if (0) {
j:
continue;
}
i = f[0];
if (a)
break;
b = i >= (b == 0);
}
if (!b) {
if (0) {
h:
goto j;
}
return 0;
}
h();
}
}
int main() {
d();
return 0;
}
```
