Yep, many moons ago, I used to run the svn tests (on Linux and cygwin) which would fail intermittently on cygwin. I didn't notice any problem with perl though. > 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.

Since I stopped running the svn tests, the number of intermittent test failures on cygwin have dropped significantly, but haven't gone away completely. I just finished the second test-suite run and, of course, t0021 ran without problem this time. Hmm, I don't think I have time to chase this down at the moment. I will keep your 'perl hypothesis' in mind for next time, however. Thanks. ATB, Ramsay Jones
