How to reproduce

The attached file was created by downloading the 5x5 no holes magnet plate from https://www.printables.com/model/250550-gridfinity-magnet-light-baseplate/files I then performed the following actions:

(All directions are POV looking from front to back of build plate)

• Lay on Face front face of model so it stands up tall.
• Cut at 28mm only keeping top
• Lay on Face right side of model so it's standing tall again with previous cut
• Cut at 24mm only keeping top
• Auto Orient
• Arrange All Objects

This should give you the same model as attached as follows:

If I now try to slice this model, orca slicer will segfault.

If I rotate the model 180 on the Z axis, it slices correctly.

Actual results

Orcaslicer segfaults and crashes when trying to slice this model

Expected results

For it to slice correctly.
