@guillett What leads you to conclude that the currently implemented behaviour is wrong ? I cannot say I am 100% certain that the existing code is correct, it took me...

Closing as stale. This might well still be one of the core issues in OF, and some ideas are starting to emerge for addressing it from a different perspective (e.g....

#857 should improve the situation a bit, and make the fix easier to express: two simulations can share the same *entities* but not the same *populations*.

Potentially a "good first bug" for Core contributors, as there is a usable workaround (instantiate two distinct `SimulationBuilder`s) so the urgency is low, and the fix is relatively clear -...

Thanks for the heads-up @magemax - taking a quick 👀 before getting back to you with an assessment.

**Suggested workaround**: remove the "recursion", replace it instead with an explicit loop (or closed-form expression) and a check on the requested period, i.e. something like `if year

[Previously.](https://github.com/openfisca/openfisca-core/pull/826) The current behaviour is the result of an explicit decision, and that decision included *not* issuing warnings. Revisiting that decision is of course possible, and I would recommend reading...

Nice! I've been bitten by this when deploying to Heroku from a Mac. Glad to know what the problem was.

Hi @Alexia - thanks for the feedback. We are currently in the process of setting up a bug bounty (to launch in the next few days) and publishing a vulnerability...

We have corrected the error and reconstituted the events leading up to it, and I'm confident your prompt notification will help in making the process more robust. Thanks again! It...
