Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org

The code is as follows:
template < int V >
struct A
{
struct B
{
template < int > friend struct V;
};
};
A < 0 >::B a;
g++ accepts the code, but clang++ rejects it:
error: declaration of 'V' shadows template parameter
template < int > friend struct V;
^
note: template parameter is declared here
template < int V >
^
