Segmentation fault with latest Rebound version when accessing orbit of a particle about rebound HOT 5 CLOSED

Just putting something together for you to reproduce this issue. In the meantime, I downgraded my Rebound version to 3.26.0, where this is not happening when analysing my data. Anything more recent than that causes a segmentation fault.

In principle SimulationArchives should be compatible across different versions. But I would recommend to save/load simulations with the same version. I just can't test all possible combinations.

This is hard to debug without seeing more of your code (ideally something short I can run myself to reproduce the issue). From what I see here, it looks like the particle for which you calculate the orbit has an invalid pointer to a simulation it is supposed to be in (each particle has a pointer so it knows in which simulation it is in). So maybe you deallocated a simulation at some point by accident?

It seems that the issue I am having is connected with analysing simulations set up/run with an older version Rebound (e.g. 3.26.0) when my analysis code runs in the latest version. I now have a few simulations that are created and run in the latest version 4.3.1 and I no longer experience a segmentation fault when being analysed while running the latest version.

Completely agree, thanks.
