Hi,

Consider the attached STL file, which appears to be well-formed and manifold.
In the Polyhedron_3 demo:
o Add STL file
o Convert to Nef polyhedron
o Convert to normal polyhedron

-> This causes a hard crash

Internally, CGAL does, indeed, attempt to throw an exception, but since the 
exception is thrown from a destructor, it won’t reach the client code and 
cause a crash.
See discussion and analysis of the crash here, together with suggestions for 
workarounds: https://github.com/openscad/openscad/issues/410

Is this a known issue or could it be addressed without patching CGAL?
