             Bug #: 54532
           Summary: [C++0x][constexpr] internal error when initializing
                    static constexpr with pointer to non-static member
                    variable
    Classification: Unclassified
           Product: gcc
           Version: 4.7.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

The following code triggers a segfault.

struct reg {
    template <typename CLS, typename T>
    constexpr reg(T CLS::*) {}
};

struct foo {
};

struct bar {
    foo a;

    // both of these trigger internal error
    static constexpr foo bar::*reg_a = &bar::a;
    static constexpr reg reg_a = &bar::a;
};
