Hi Armin,
thank you for your reply.
I've used both for reading and writing the Xdmf3 choose.
In attach you can find the output of the saving of the polyhedron.vtu
(saved.xmf and saved.h5) from the Windows machine.I've tried also to repeat the procedure (reading of your xmf file) on a Linux workstation and the behaviour is different: it seems that randomically the crash happens again (once on about ten tries) and sometimes it seems that the topology has a connectivity error (see the image in attachment), while for the most of the times it seems to do the right job. I've tried also another case, a little bit heavier: a polyhedral mesh read from the vtu in attach (cube.vtu) and saved with the Xdmf3 writer. Trying to re-read the xmf version of this geometry always produces a crash also on the Linux machine. Thank again for your help.
