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.

Hello Drew,
I updated just all dolfinx packages to 2019.2.0~git20210130.c14cb0a-3.
(That drew updates for libbasix0 and libpetsc.)
But the fault does appear there too.
Kind regards,
Bernhard
