[Bug c++/16784] New: Wrong warning : control reaches end of non-void function

[sylvain dot pion at sophia dot inria dot fr]

g++ 3.5, with -Wall, emits a buggy warning for the code below.
g++ 3.4 works fine.

--------------------
struct A {
  A() {}
  ~A() {}
};

int k()
{
  A K;
  bool b;
    
  if ( b ) {
    A G;
    return 0;
  }
  else
    return 0;
}
--------------------

spion@termite:~/GCC> ./Linux/bin/g++ -Wall -c warn_3_5.C
warn_3_5.C: In function `int k()':
