As a note some code is currently commented out until two different bugs are fixed

YoYoGames/GameMaker-Bugs#7799

The tests shouldn't provide workaround for bugs. They should expose the bugs so we can see when they are fixed. So please, make sure to let the test fail... or if it is a crashing bug.... add a dummy:

assert_true(false, "This code should be uncommented when the bug is fixed!");

so it will not crash but still fail

@DiasFranciscoA Having that code uncommented prevents a compile. Additionally it will not be fixed until GMRT as mentioned by Russell YoYoGames/GameMaker-Bugs#8041 (comment)
But you bring up a great point with the assertion there. I'll add that to the tests now
