>Description:
When I try to set a breakpoint on a constructor, I get
bizarre menu choices in some circumstances: if I compile
the following:

class C {
public:
  C() {};
};

int main()
{
}

If I actually declare a variable of type c somewhere, the
?HERE's get replaced by something more reasonable.

It's not entirely clear to me _exactly_ what the
conditions are to trigger the bug.
