Crashes when optimizing a 3d mesh
I have a 3d torus shape that causes GMSH to crash when trying to optimize a 3d mesh. To reproduce:
- Open the attached GEO-file.
- Click on Mesh -> 3d to generate a mesh.
- Click on Mesh -> Refine by splitting.
- Click on Mesh -> Optimize.
This causes my GMSH 2.11.0 to crash. I have attached the GEO-file and the ~/.gmsh-errors log.
In the preferences Mesh -> General, I have "Delaunay" in the "3D algorithm" field. If I instead select "Frontal", the above steps do not lead to a crash.
