            Bug ID: 61182
           Summary: Forming pointer to qualified function type
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org

Minimal test

The attached code does not compile on gcc 4.9 but compiles on clang 3.4 and gcc
< 4.9.

Accessor decompose the type with C = "C" and T = "int () const" in the first
call of make. Then same_type creates a T* and removes the pointer to get back
to the same type. GCC 4.9 complains that we cannot create a pointer to a
qualified pointer type even though we never instanciate it.
