--- Comment #7 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Here is a semi-cleaned up testcase without a special name (_setjmp) being
involved:
```
int f() __attribute__((returns_twice));
struct c1 {
  virtual int bb(void) const { return 0; }
  bool f1(int a)
  {
    return a && !bb();
  }
};
struct c2 final : c1 { void f2(int); };
void c2::f2(int a) {
  if (!f1(a)) f();
}

```
