Exact steps for others to reproduce the error
Select Boid, play animation, stop, rewind to frame 0,
Select Fluid, play animation, then crash

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.

I've built
ccd291aafb
snapshot for the reporter to try. I'm assuming it's the latest 2.7 snapshot.See also https://bugzilla.suse.com/show_bug.cgi?id=1126163
I've received the OK to distribute the original file from the author, but even after compressing it, the size is 31MB. 11_Physic_Systems.blend.gz
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:

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!

Changed status from 'Confirmed' to: 'Needs User Info'
I have re-triaged this report and can not reproduce it.
Can you please check if this is still an issue in latest build?
