Blender Version
Broken: version: 2.80 (sub 53), branch: blender2.7, commit date: 2019-04-03 23:27, hash: 0e78e3038d
Worked: (optional)

Short description of error
Sometimes boolean don't work properly. I'm not sure what is the nature of bug. But one part is - it reproduced when I apply few booleans modificators that intersect (objects) in space to main object. And mainly it happened(more faster) on overloaded objects or when you have a lot boolean modificators on 1 complex object.

So.. this bug actually lead to another problem at once (I think they are linked/related) - that you can't create 1 complex object that will include into himself more than 1 primitive that might intersect between themselfs (this happened often too to me)

Additional: btw same situation if you will use complex (more than 1 primitive inside with intersect meshes) main object as and boolean to him just one cube.

Exact steps for others to reproduce the error
First file from default factory settings. There are cube minus all other objects. Select and move Monkey head to see that that boolean is broken (when it will interselect with other booleans operands - you'll see glitch) https://i.gyazo.com/d0e449790b3c337c2ffe0bac7f66518c.mp4

Second file show that you can't "minus" operand that have complex form (where vertex and edges intersect or have same position ) https://i.gyazo.com/e344bd16c613fd5faf042e8c599a1a0a.mp4
Select mesh named "operand B" and go to edit mode. Then move any of both primitives toward to another - to create interselection between them. You will see glitch.
