Bug ID: 71082
   Summary: Internal compiler error when create initializer list
with pointers to members
   Product: gcc
   Version: 6.1.1
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c++
  Assignee: unassigned at gcc dot gnu.org
  Reporter: farmaazon at gmail dot com

preprocessed file of code in bug description

I try to compile the following code without any additional flags (just g++
gcc-6.1-bug.cpp)

#include 

class A {
public:
int x;
int xplus1() { return x+1; }
int xplus2() { return x+2; }
};

int main()
{
const auto members = { &A::xplus1, &A::xplus2 };

A a;
a.x = 12;
int y;
for (auto member : members)
y = (a.*member)();
return 0;
}

The result is an internal compiler error
