When I compile this test case with mainline c++:
struct S {};
struct T : S {};
int f(const T*) {}
void f(T*);
int main() {
S* s(0);
int a = f(static_cast<const T*>(s));
int b = f(static_cast<const T*>(0));
}
I get this:
foo.cc: In function int main():
foo.cc:7:37: error: void value not ignored as it ought to be
This seems wrong. I'm casting the value, so it should pick up the overload
which returns an int. Note in particular that it works when casting 0 but
fails when casting a real object.
