See Ronald's reply above in msg331101. I believe his point is that there is nothing you can do to make this safe. And it's not a new problem with 10.14 or 10.13. What is new is that Apple is trying to more forcefully make you aware of the danger by causing the runtime to try to catch and crash these cases earlier rather than permit them to perhaps silently cause failures later.
