Please test the latest daily build to see if it has been fixed already:
https://builder.blender.org/download/

If not, we need a .blend file to reproduce the issue. Referencing one that is available along with a book is not very practical for us.

That build also shows the same crash.

I've managed to reproduce the bug, strangely I couldn't yesterday, so it's not a graphics card thing, I've got simple intel graphics. The reporter has reproduced with the above snapshot debug build built with -fsanitize=address, -DWITH_MEM_VALGRIND:BOOL=ON and -DWITH_ASSERT_ABORT:BOOL=ON and also with the 2.79 tarball from https://builder.blender.org/download/
There's several backtraces from https://bugzilla.opensuse.org/show_bug.cgi?id=1126163#c8 down.

I can also reproduce this with both 2.79 (git) and 2.8.

Just to be more clear with the reproduction steps:

Open the attached file
Switch to the "Boid" scene
Play animation for a while and stop
Rewind to frame 0
Switch scene to "Fluid"
Play animation until it crashes

This isn't a recent regression, goes at least back in 2.70 (where things crash on random at the step 3 from @ZedDB's instruction).
I don't personally think it worth spending time on this now, and would rather encourage new particle/physics development.

If someone else wants to look into this, be my guest!
