[Issue 11657] Pass array literal to typesafe variadic argument on stack

[via Digitalmars-d-bugs]

--- Comment #2 from hst...@quickfur.ath.cx ---
Really? variadic arguments are not allowed to escape? Then there is a glaring
hole:

    class C {
        int[] a;
        this(int[] data...) {
            a = data; // compiles
        }
    }

This case needs to be prohibited, otherwise we end up with bug #5212.
