Comment (by SimonKing):
Here are test failures on my `OpenSUSE` laptop.
Most of the tests fail because of changes in the random generator or
because of slightly changed error messages or because of changing
documentation in GAP or simply because of testing against the version
number.
Here are more serious problems:

That seems to be a rather serious error: `G = AdditiveAbelianGroup([2,
3])` in the first example, and `G = AbelianGroup(2, [2,3])` in the second
example - so, why is there a change in the isomorphism types?
In sage/coding/linear_code.py are a few crashes, like this:

Note the crash in the last example. A similar crash is:

}}}
Several tests in latin.py fail, probably because of changes in the random
generator. Couldn't one test instead whether the squares really ''are''
latin?
A strange one:
{{{
