Assertion failure in Mesh_3

[sloriot]

In https://cgal.geometryfactory.com/CGAL/testsuite/CGAL-6.0-Ic-181/Mesh_3_Examples/TestReport_lrineau_Debian-Stable.gz

There is for the first time this assertion failing (I don't see how it could be related to PRs under testing so we can assume it's not):

CGAL::Random()::get_seed() = 1709042793
terminate called after throwing an instance of 'CGAL::Assertion_exception'
  what():  CGAL ERROR: assertion violation!
Expr: outdated_cells.size() == cells_backup.size()
File: /mnt/testsuite/include/CGAL/Mesh_3/C3T3_helpers.h
Line: 2628

I tried to reproduce the error with master/integration with the same seed but I don't have the assertion failing (TBB is used to it's not that surprising)
