GiNaC indeed shows interesting behaviour. Just the first test on 4.3 is: timing commutative expansion and substitution.... size: 100 200 400 800 time/s: 0.064 0.30 1.4 6.2for 4.5 timing commutative expansion and substitution.... size: 100 200 400 800 time/s: 0.080 0.36 1.6 7.4 and for 4.6 timing commutative expansion and substitution.... size: 100 200 400 800 time/s: 0.076 0.37 1.7 8.2 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.
