|Perl: the Markov chain saw|
Hmm.... thanks for pressing this, demerphq. You appear to be right about not needing so many mortals. I think the trick is to avoid incrementing any refcounts (as I was doing after hv_store()), and only mortalize the RV I am pushing on the stack. This is basically what you said, but the code comes out a bit different from what you said:
So I'm just creating all "intermediate" variables non-mortals, not incrementing any refcounts after av_push or hv_store(), using newRV_noinc(), and mortalizing just the RV that's pushed on the stack.
Does that seem right? Sure looks cleaner...
In reply to Re^6: perlembed: mortalize an AV, get "Attempt to free unreferenced scalar" - don't mortalize, leaks memory
