I've not spotted t0021 failing in that way, but it sounds like the same class of problem. I dig into these failures when I see them, mostly by running the script a few hundred times until I get the failure again, and they've always been Perl itself segfaulting. That points to the problem being in Cygwin's Perl package rather than Git, and it's very unlikely to be anything that's got worse in v2.15.0. I've never managed to get further than pinning the blame on Perl, though. If you manage to reproduce the failure and it turns out to be something different, or you manage to dig into the failure in Perl itself, that'd be some very interesting news. Adam
