Also typo fix in comment

Unsure why the int() conversion needs to happen twice

Also remove a debugging statement

Replaced one instance for profiling

- hammer-parse-apply wasn't clearing the pointer to the desired stack frame
- Reproduction steps: hammer-parse-step N, hammer-parse-apply, hammer-parse-step 1
