Summary: Dependent conversion function names looked up in
dependent bases
Product: clang
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++
AssignedTo: [email protected]

This code is ill-formed. Unqualified names should not be looked up in dependent
base classes, no matter whether they are dependent or not, according to the
Standard.
template<typename T>
struct A {
operator int() { return 0; }
};
template<typename T>
struct B : A<T> {
int f() { return operator T(); }
};
int main() {
return B<int>().f();
}
Clang accepts it, though. And it's easy to construct an rejects-valid for this,
just add another non-dependent base that also has an "operator int" declared,
and you wrongly get an ambiguity diagnostic.
