All right. I recompiled Sage without chomp. Now, beyond the binary tree
issues with bliss (#18698), I have failing doctests related to
gap_database (all of them are marked with #option - database_gap) in
- sage/groups/perm_gps/permgroup_named.py
- sage/tests/gap_packages.py
- sage/groups/perm_gps/permgroup_named.py
Looks to a failure similar to the one reported by
Emanuel Charpentier on sage-release. The gap packages fail to be imported
sage: import sage.tests.gap_packages
sage: sage.tests.gap_packages.test_packages(['atlasrep'])
Status Package GAP Output
+---------+----------+------------+
Failure atlasrep fail
sage: sage.tests.gap_packages.test_packages(['tomlib'])
Status Package GAP Output
+---------+---------+------------+
Failure tomlib fail

according to #16364, chomp could lead to this kind of things. But it is not
in your list !!

For binary trees, I have made http://trac.sagemath.org/ticket/18698 that
needs review.

Indeed, the failure for binary trees should come from canonical labeling.
It would be enough to
change the doctest so that they are no longer sensitive to that.
I am no longer that sure that TOPCOM is the other problem. What other
package is delaing with homology ? chomp ?

I would suspect that topcom should be responsible for the homology
errors.
No idea for what happens to binary trees. They seem to be reversed
(left-right symmetry ?)
That could be 'bliss'. It becomes the default algorithm to compute
automorphism groups of graphs and canonical representatives. Those
canonical representatives will be different from the previous ones,
though.
