Thank you for report. I can reproduce this bug on Win.

This issue should be fixed in the next release.

The crash now is fixed on master by swapping the triangulation library with a proven glu tesselator (written in 1994 in plain C by SGI). The fix will be part of the Slic3r 1.42.0-alpha6.

While the triangulator does not crash, if the input mesh is broken, the cut is not always triangulated. Namely, inverted parts are not triangulated.

Closing.
