System Information
Window 10 x64, Nvidia GTX970
Ubuntu 14.04 x64, Nvidia 675mx

Blender Version
Broken: 2.76.5 5e974a3

Short description of error
Bmesh boolean difference error (B - A):

if operator mesh (A) has one or more edges that are coincident with edges on first mesh (B) or its faces, the operation fails.

I don't know if it's same error posted [#47011 ]] or [ https:*developer.blender.org/T46988 | #46988

Exact steps for others to reproduce the error
See .blend attached
Bmesh_boolean_fail.blend

Edit, adding the example file from #51236 since its a good test-case for debugging:

boolean.blend

And another from: #52825 (overlapping edge/vertex)
potentialBmeshBug_simple.blend

Sounds like duplicate of #46988 actually?

#46988 is infact zero area faces, re-opening this one.

Note, these edge-cases are detected and handled. there are some cases where exact overlap checks fail - this needs some investigation.

Boolean still not working with "blender-2.80.0-git.8f1951f555f5-windows64".
Added a simple file:

Same issue here (2.81a, macOS)

{F8308525,size=full}

Note that moving the door frame all the way through the X axis, the boolean intersection modifier will behave like a union

This is fixed if one uses the new Exact solver. commit 9e09b5c418
