            Bug ID: 66210
           Summary: Variable template specialization does not work with
                    alias-declarations
           Product: gcc
           Version: 5.1.0
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: bruno.manga95 at gmail dot com
  Target Milestone: ---

Created attachment 35571
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=35571&action=edit
testcase

In code such as the following, alias-declarations causes a variable to be
instantatiated from the non-specialized variable template

using resultType = const char*;

template<typename T>
T pi = (T)(3.1415926535897932385);

template<>
resultType pi<resultType> = "pi";

NOTE: using a typedef does not generate the same error and the code compiles
