Hi Marius,

When I get home I'll run it again on my Mac Mini using your _latest (64bit) image and send you the crash log.  It was segfaulting there as well when I tried it, but perhaps something has been changed/fixed since.

I worked around the problem by rendering the intersection() parts to unit-scaled STL and import_stl() instantiating them into the main design.

There's always a way. ;-)
