src/test.hpp:26: error: specialization of ‘template<class T> void N::X::F()’ in
different namespace
src/test.hpp:14: error:   from definition of ‘template<class T> void N::X::F()’
src/test.hpp:28: confused by earlier errors, bailing out

namespace N {
 struct X;
}

struct N::X
{
 template < typename T >
 void F();

 template < typename T1, typename T2 >
 struct G
 {};

 template < typename T2 >
 struct G < int, T2 >;

};

template <>
void N::X::F < int >()
{
 std::cout << "F specialization" << std::endl;
}

int main()
{
 N::X x;
 x.F< int >();
 return 0;
}

If I am not wrong, the explicit specialization of "F()" must be defined in
namespace scope, but why gcc "crushes" from this incorrect code ?

Thanks in advance.
