      The attached file.cpp has these lines in it ...

      struct X {
    const char *name;

    constexpr X(const char *n) : name(n) {}

    static constexpr X x1() { return X("x1"); }
    static constexpr X x2() { return X("x2"); }
};

void f()
{
    X::x1();
    X::x2();
}

      Build it ...

      % cl6x -s file.cpp
"file.asm", ERROR!   at line 58: [E0300] Symbol _ZZ1fvEs has already been

>> Compilation failure

      Inspect file.asm to see that two strings "x1" and "x2" are created, but they both have the same label _ZZ1fvEs.
