Version mismatch could cause problems.
Bernhard, can you provide the versions of each of the packages you're
reporting on
(dolfinx, eigen3, gmsh) ?
Hello,
these are the versions I have used in this test VM.
Would it be possible that libgmsh should use
the Memory.h below /usr instead of ./contrib ?
You could configure Gmsh with "cmake -DENABLE_SYSTEM_CONTRIB=1", which
will instruct Gmsh to use "system" versions of the contrib packages if
they are available.
That is almost certainly a good idea, thanks Christophe.

That could be the mismatch, if gmsh used its own copy of eigen different
from 3.3.9. Alternatively if libdolfinx-dev was built against an older
version of eigen then it might make a discrepancy.
Dolfinx has just been updated in unstable. Bernhard, you could check if
the rebuild for this new version fixes your problem. But likely we'll
want to apply Christophe's flag to the gmsh build.
