I recently was able to produce a very small test case that reproduces this issue reliably on some machines:
Your suspicion about a race condition may very well be correct: I can easily confirm the problem on both iron and virtual smp, but not on a single core virtual.
I have two instances of your test case running for half hour on the same core, without any problem: 30k cycles without hickup. Apart from the immediate effect exposed by your script, I have reason to believe that the root cause also affects other running (smp) processes. bartels -- 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
