This is ice-on-invalid: the key of an AA must be a type. Although the declaration is accepted when the -g flag isn't used, that's also a bug. It's pretty meaningless -- there's no way to put anything into the AA! The declaration should be rejected.

PATCH: This is very easy. Just disallow tuples as AA keys.

In mtype.c, in Type *TypeAArray::semantic(Loc loc, Scope *sc), at line 3293:

    switch (index->toBasetype()->ty)
    {
    case Tbool:
    case Tfunction:
    case Tvoid:
    case Tnone:
+    case Ttuple:
        error(loc, "can't have associative array key of %s",
index->toBasetype()->toChars());
        break;
    }


And here's a test case for the test suite. Should compile without error.
---
template Tuple(T...){
    alias T Tuple;
}
// Bugzilla 3336
static assert(!is(int[ Tuple!(int, int) ]));
