[Bug c/33327] New: gcc 4.{1,2} fail warn uninitialized

["mark at hindley dot org dot uk" <gcc-bugzilla at gcc dot gnu dot org>]

gcc 4.1 and 4.2 fail to warn about an uninitialized variable in the following
testcase. gcc 3.3 correctly warns.

int 
foo(int i)
{
  int err;

  if (i) {
    err = 1;
  }
  return err;
}

Verified on
