testing/freecad: FEM meshing with gmsh causes FreeCAD to crash
FreeCAD currently fails to work with Gmesh while using the FEM workbench. This seems to be related to the use of VTK9 as indicated here, and is a problem across most packaged versions of FreeCAD as the last supported version of VTK was VTK7. When trying to create a mesh, a repetition of the following error is thrown:
2021-11-29 04:06:46.824 ( 10.856s) [60A68490] vtkCellArray.cxx:551 ERR | vtkCellArray(0x7fd0f74462c0): Invalid location.
There is an upstream patch to make FreeCAD compile with VTK9, but it is pretty similar to the patch currently used. The proper solution is probably to upgrade the SMESH version but that might introduce other problems.
Assigning to myself, just creating the issue to create a centralized place to keep track of things.
