Can confirm the issue. It seems to be caused by array modifier delivering broken topology. This screws up boolean modifier here and could potentially break other areas of blender. So this is first thing to be fixed before we can check if there are more issues here.

I've simplified the case to a single object:

You can apply modifier and run mesh validation and you'll see lots of unused loops.

@Germano Cavalcante (mano-wii), @Bastien Montagne (mont29) or maybe @Patrice Bertrand (PatB) can help having a look here? :)
