Crash when writing abaqus mesh file

I’ve run into problems when trying to export Abaqus meshes: on Linux 6.8.0-94-generic netgen v6.2.2601 crashes while writing (typically, the nodal coordinates) and produces a core dump. Most other mesh export formats, however, seem to work O.K. from the same .vol file. Also, Abaqus export of similar meshes routinely ran w/ earlier versions of netgen.

A python file defining a mesh showing the behavior is attached
