Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

aeec19d2e7Short description of error
When boolean-union two objects there is a chance of them merging where it deletes all intersecting faces including the entire boolean target mesh.
Exact steps for others to reproduce the error
Create a boolean modifer on the object "base" and set it to "union". Set the object target as "broken" and apply the modifer. It results in a hole where the "broken" mesh intersected with the "base" object. This can alternatively be fixed by slightly moving either object.

I cannot reproduce this with either blender 2.78a or current development versions.
Is this an OS-specific problem?
