Yes, can confirm.

@Howard Trickey (howardt) : could you have a look?

It’s not just union. I got a crash using difference with solver set to fast. Seems it sometimes deletes the entire mesh and that’s when the crash happens.

I'm not sure I am doing the right thing here because I cannot make a crash, either with Fast or Exact mode. I took one or the other of the two objects and added a Boolean modifier with type = Union and object = the other object. Was that what was intended to create the crash?

With Exact solver, the code did not do a proper Union. I think the one or both of the objects has self intersections. With the new 'self' flag I added to the modifier, if that option is checked, the Exact solver makes a proper Union. (Other boolean op types seem fine too.) I will close this if/when Marcin can check with a new build that has the 'Self' flag.
