--- Comment #2 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
Ops, I got confused by the testcase and this is not actually a duplicate.

void bar(int *a);

int baz (void);

void
foo(int *b)
{
  int a;

  if (a) {
    *b = 0;
    return;
  }

  bar(&a);

  a = baz();

  *b = a + 2;
}

In gcc 4.9.2 you need at least -O1 to get a warning, however, it seems that in
GCC 5.0 r220306, -O0 is enough. Thus, I would consider this fixed.
