hokein added a comment. Thanks for the report and revert, and sorry for the failures and the late response (was OOO on Friday).

Thanks for diagnosing it. Yeah, this is the root cause. `cook` returns a tokenStream (which has its own payload), and this token stream is a temporary and being destroyed after the `stripComments` statement, and we have dangling pointers.
