            Bug ID: 85356
           Summary: [7/8 Regression] ICE with operator=
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: reichelt at gcc dot gnu.org
  Target Milestone: ---

The following valid code snippet triggers an ICE since GCC 7.1.0
when compiled with "-std=c++1z":

==============================
struct A
{
  A& operator=(int);
};

void foo(A&(A::*)(int));

template<int> void bar()
{
  foo(&A::operator=);
}
==============================

bug.cc: In function 'void bar()':
bug.cc:10:20: internal compiler error: in type_throw_all_p, at cp/except.c:1185
   foo(&A::operator=);
