            Bug ID: 57887
           Summary: nested non-type template parameters not declared in
                    this scope
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org

Hi, when trying to compile the following:

struct B
{
        template<int N>
        struct A
        {
                int X = N;
        };
};

I get the error: 
g.cxx:6:11: error: 'N' was not declared in this scope

Things work fine when I make X a static const(expr), or when I move A outside
B. The above code however works fine within clang, and I could not find any
wording that would make N suddenly not being available within A, especially
since when you add teh following member function to A (but remove X), it
compiles fine:

void foo( ) { int x = N; }

so it /somehow/ is in scope.
