FreeCAD with netgen use flag enabled, compilled against media-gfx/netgen-6.2.2302 crashes on trying to generate mesh from any shape. Reproducible: Always Steps to Reproduce: 1. Create new empty document 2. Using Part or Part Design workbench create simple primitive, any will do, I can confirm this happens with cube and others 3. Switch to Mesh workbench and do "Create mesh from shape" 4. Switch to Netgen tab and click "OK" Actual Results: paź 01 19:52:24 preciosat3500 org.freecad.FreeCAD.desktop[129000]: Program received signal SIGSEGV, Segmentation fault. paź 01 19:52:24
