struct S
{
    string g() { return ""; }
    void f() { mixin(g()); }
}


Making g() static stops DMD from crashing.

There's another problem. This fails to compile:

struct S
{
    static string g() { return null; }
    void f() { mixin(g()); } //line 4
}

z.d(4): Error: argument to mixin must be a string, not (null)

(Tested with dmd v2.041.)

PATCH(against 2.042): This is trivial.

// interpret.c line 2569:
    if (pthis && fd)
    {   // Member function call
    if (pthis->op == TOKthis)
-        pthis = istate->localThis;
+        pthis = istate ? istate->localThis : NULL;
    else if (pthis->op == TOKcomma)
        pthis = pthis->interpret(istate);


The second issue is that mixin(null); is never allowed. It's completely
unrelated to this bug. Create a new bug for it if you think it matters.
