Hi,

I will look into those later today, but frankly I don't understand the rationale of this kind of testing: if I fix a bug in 4.5, which is part of the code in the .so, and at the same time I adjust only the 4.5 testsuite to match, of course the 4.4 testsuite will show spurious regressions. And since we are not removing testcases from the testsuite, I don't see what genuine problems we are hoping to catch with that kind of obscure testing... Bah
