Btw., does that testcase fail in 1.7.9 as well? I'm pretty sure it did. I think all the tests passed the last time I released this package (2011-09-10), but I might have been testing against a snapshot. It's hard for me to tell now. If I just install 1.7.9 on my system, things like /bin/ls stop working. The compiled tests don't run, either. FYI, the test was passing with 1.7.10 and the 20120214 snapshot. It didn't start failing until your last snapshot (20120215). -- David Rothenberger ---- daveroth@acm.org Don't panic. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
