// PoC: (function func(arg = function () { print(func); // SetHasOwnLocalInClosure should be called for the param scope in the PostVisitFunction function. }()) { print(func); function func() { } })(); // Chakra fails to distinguish whether the function is referenced in the param scope and ends up to emit an invalid opcode.
