            Bug ID: 61500
           Summary: [C++11] [4.8/4.9 Regression] Can't take pointer to
                    member referenced via member pointer template
                    parameter.
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vmarko at google dot com

struct X {
  int i;
  int j;

  int foo(int X::* ptr);

  template <int X::* ptr>
  int bar();
};

int X::foo(int X::* ptr) {
  int* p = &(this->*ptr);  // OK.
  return *p;
}

template <int X::* ptr>
int X::bar() {
  int* p = &(this->*ptr);  // gcc 4.9.0: OK in C++98 mode, fails in C++11 mode.
  return *p;
}

gcc 4.9.0, C++11:
test.cc:18:24: error: lvalue required as unary '&' operand

Reproduced with gcc 4.9.0 from AOSP prebuilts (aarch64-linux-android) and gcc
4.8.0 from AOSP prebuilts (x86_64-linux-android). Works fine with gcc 4.6.3 on
host (x86_64-linux-gnu).
