Which means that since I'm using a C generated parser I should use
destructor. But destructor will be called after each successful action
or after each failed parsing (to which an action never gets called but
the given value is actually allocated)?
Only when the parser unwinds the stack in a parse error recovery
attempt, or so I remember (it's easy to check the written C-parser).
You still to do normal cleanup in the rule actions.
