The following compiles, but causes a segmentation fault when run:

    void foo(ref string s)
    {
        s = "hello yourself";  // Anything that changes s will do.
    }

    void main()
    {
        foo("hello");
    }

I'm guessing that the compiler should catch this and provide an error saying
"hello" is not an lvalue.  At least that's what it does if one tries something
similar with an array literal.
