            Bug ID: 63290
           Summary: [C++11] alias declaration with exception specification
                    should cause compilation error
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: kariya_mitsuru at hotmail dot com

The sample code below should cause a compilation error but it can be compiled
successfully by g++.

================================
using FP = void(*)() noexcept;
================================

According C++11 standard [except.spec] 15.4/2, "An exception-specification
shall not appear in a typedef declaration or alias-declaration."


Note: Another sample code below causes a compilation error.

================================
typedef void(*FP)() noexcept;
================================
