            Bug ID: 109958
           Summary: ICE: in build_ptrmem_type, at cp/decl.cc:11066 taking
                    the address of bound static member function brought
                    into derived class by using-declaration
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---

struct B { static int f(); };
struct D : B { using B::f; };
void f(D d) { &d.f; }

<source>: In function 'void f(D)':

function to form a pointer to member function.  Say '&D::f' [-fpermissive]

This appears to have been broken somewhere between 4.7.4 and 4.8.1.
