GiNaC indeed shows interesting behaviour. Just the first test on 4.3 is:

I assume that the numbers are times in second, so it is indeed not good. Can I
easilly run the individual tests by hand? Do you have any idea what is going
wrong here?
Yes, one can run the individual tests by hand. And it should suffice to
focus on the first one, as you did. All the follow-up regressions are
most likely due to the same problem. And no, I have no idea what's up yet.
