Bug ID: 84030
Summary: Name lookup in presence of namespace
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: Zahira.Ammarguellat at intel dot com
Target Milestone: ---
In the code snippet below gcc doesn't give any diagnostics:
struct A_ { };
namespace N_ {
struct A_ {
int g()
{
return 3;
}
template<class T> operator T()
{
return T();
}
};
}
int main(int argc, char *argv[])
{
N_::A_ a;
int b = a.operator A_().g();
return b == 3;
}
gcc seems to be choosing "N_::A_::A_" operator. But in reality there should be
ambiguity between that and A::operator?
Both clang and MSVC fail to disambiguate it.
