Crash triggers when object has zero faces. In code, it occurred due to null pointer access mface->v4
I guess fix will be a simple if check.

Crash triggers when object has zero faces. In code, it occurred due to null pointer access `mface->v4` I guess fix will be a simple `if` check.

do not know if the bugs from the list of first fixes are still being processed and fixed. If not, was it correct to include a crash in this list?

Not sure which "list" or "list of first fixes" this relates to?

Also not sure what exactly this should mean?

In my opinion this is a legit bug, but one in a part of blender (the old particle system -- which is "End of Life") which is unlikely to see fixes from blender devs, any contributed patches are of course welcome.
As triagers, we can just confirm this, it is up to the #nodes_physics team to close this (or lower priority / mark as Known Issue).
