In my actual program, the code to the function is generated at runtime, so I can't use a normal closure. Changing the respective 'my' to 'our' seems to have fixed the code, but I'm really bothered by the inconsistency that it works when I have that print statement.

(Maybe the print statement prevents it from making some optimization which isn't valid in the situation?)
