[Bug c++/41341] New: gcc fails to reject inclass partial specialization of iherited class template

["tomek at jot23 dot org" <gcc-bugzilla at gcc dot gnu dot org>]

In the attached code partial specialization of struct apply in struct
METAFUNCTION2 should be rejected according to C++ Standard 14.7.3/3:

A declaration of a function template or class template being explicitly
specialized shall be in scope at the point of declaration of an explicit
specialization.

What's more troublesome is a fact that specialization in METAFUNCTION2 seems to
affect the template in METAFUNCTION. The program produces:

int
double
double

while I would expect:

int
HELPER<float, double>
double
