Are you using Strict?
Without Strict the slightest spelling mistake can cause strings to be uninitialized objects that will crash if invoked like your first example.
You are in Debug mode?
BTW a crash on Apple I usually regard as an event that will cause the OS to dump a large log into the output window. If you are in debug mode, the debug tree on the right should allow you to analyze the state of your code for a standard BlitzMax runtime error.
If the program just silently exits completely (stop button disabled) does it say anything in the output window?
