Runtime errors with some of my games

Jumping on the inkcpp bandwagon to leverage the opportunity to publish my stories for the eenk platform.

Not having much luck so far.
Some errors I'm having:

The simplest to describe: Running the "Storylet" example from Inky
Source: Storylets.ink.zip
Error: No 'done' point recorded before finishing choice output
This one is trickier, it only happens after the first choice
Source: PaniqueAMandonez.zip
- Error Case 1:
  To reproduce: choose "Commencer" (1) and then "Observer le village" (choice 1)
  Error Output should be empty after getline!
- Error Case 2:
  To reproduce: choose "Commencer"(1) and then "Descendre" (choice 2)
  Error something looking like it's going on an infinite loop, cpu at 100% but no output

All these run fine in inky, inklecate, and inkjs/web.

Thanks for opening the issues.

I can reproduce the first issue (different error, but still an error, so I will start there investigating)

The second one I cannot reproduce since I think there are files missing in the .zip (there is just one .ink file)

I will update if I find a trace.

My bad, here is the complete ink project PaniqueAMandonez.zip

And thank you for looking into it !

This was a fun chase. I found many edge cases we did not encounter yet. Would you mind checking out PR #173 and validating that it solves your problems?

fixup! fix(runtime): crashes and hangs from choice/thread scoping bugs …

I've not been so eager to test a PR in ages!

Storylets : 🟢
Mandonez : 🟠
- Abovementionned errors fixed : 🟢
- But I've hit a new bumps in the road after a handful of turns :

To reproduce, using the PaniqueAMandonez project :

echo "11111433232214" | fold -w1 | inkcpp_cl/inkcpp_cl -p PaniqueAMandonez.ink
gives Unhandled ink runtime exception: Trying to access output stream prior to save point!

echo "1232322142" | fold -w1 | inkcpp_cl/inkcpp_cl -p PaniqueAMandonez.ink
gives Unhandled ink runtime exception: Cannot insert data before last save point.

🤔 They look like twin errors.
(tbh, this very much look like errors I had when I made tinta and I had to resort to comparing listing of bytecodes executed between the reference implem and the new one and it took ages, and if I knew C++ I'd offer my help 🙇🏼‍♂️ )

Ok, back in the tranches it goes. Thanks for providing the examples and an direction to check ^^

This looks funny;
If I execute it under UNIX I can reproduce your error
~~But if I execute it under Windows, I get: So yeah seems like undefined behavior~~
echo "x" | folud -w1 under windows results in

"
x
"

:(

I updated #173 now your examples run. There was an error in the rollback.
Until now, inkcpp was not allowed to access data before a rollback point if not for printing, but tags and string values use the same mechanism, so they need to be allowed too to access data before a rollback point.

So I hope you can verify that it is fixed, and I'm thrilled if you find the next input sequence to break inkcpp.

You're going to hate me :
add a "2" at the end of the first sequence (111114332322142) and you get the Cannot insert data before last save point. error again.

But, I've found that:
with inklecate at that point, you get

while, with inkcpp, you get

Notice the coma?

Are all my problems coming from my usage of tags ? If that's just so, we can call it a day and I can totally live without them for the forseeable future!

Annnnd 🥹 I also stumbled upon a Unhandled ink runtime exception: _ref_stack and _stack should be in frame sync! with that minimal code.

Currently I'm still thankful for the rigorous testing

I think I fixed your current bugs, so it's time for round 4. ^^
(see #173 for the new commit)

I've managed to finish the game ! 🎉

fix(runtime): crashes and hangs from choice/thread scoping bugs #170 (#…

Fixed in #173

(I can confirm the Storylets example now works in the e-ink simulator of eenky IDE at https://github.com/t0mg/eenky/releases/tag/eenky-nightly-20260920-54)

Just ran some more exotic tests and everything is running smoothly!

Thank you for your hard work!
