When 'Display modifier in viewport' of Bevel modifier is ON, this phenomenon occurs.
If you carry it out after you turned it off, this phenomenon does not occur.
I think that this is a bug.

That seems to be it, also moving the particle modifier above the bevel modifier keeps it from crashing.

I tried this on OSX and could not make it crash.
It would help if you can reduce your .blend to the simplest form to find what exactly makes it crash.
(ie. cube with bevel and particle?)

Here is the simplified version of the file and the crash log for it. It only crashes when X Mirror is on.

This does not occur when I replace Bevel modifier with a different thing.
For example, it is subdivision surface.
EXCEPTION_ACCESS_VIOLATION occurs and crashes.

Confirmed, issue is in DM evaluation code actually, never clears the deformedOnly flag when evaluating a generative modifier!!!
