Test case:

-----------------------
void main() {
    const a = [4:0];
    const b = [4:0];
    assert(a == b);
}
-----------------------

This causes a NULL-pointer exception in _aaEqual. The problem is _aaEqual's
signature is

    int _aaEqual(TypeInfo_AssociativeArray ti, AA e1, AA e2)
  //             ^^^^^^^^^^^^^^^^^^^^^^^^^

but the typeid of a const AA is a TypeInfo_Const, so the 'ti.keys' used later
is invalid.
