> Thanks for the suggestion. I'd like to keep it the way it is though, so that the assert message contains the `has_last_frame` & `java_call_counter` values. (this was one of the reason I did this refactor as well, since the assert I was hitting out of those 3 didn't contain that info).

You can keep the assert inside `verify_frame_info()` which dumps additional data. (Yes, it's a bit confusing: assert inside an assert :-) )
