Thanks for the testcase. I found the problem. In 2.2.1 was a use-after-free bug in the file locking code which I fixed in 2.3.0... just wrongly. It fails to work in certain cases when locking collisions occur. I fixed this in the git repo. I uploaded a new developer snapshot to https://cygwin.com/snapshots/ Please give it a try. > The upcoming Perl MCE 1.7 release does away with file locking and > works with 2.3.0-1. Uh, please don't do this. This is a bug in Cygwin 2.3.0, and the right fix is to release Cygwin 2.3.1 end of this week, not to change other packages to workaround this bug. > p.s. Thank you for Cygwin Thanks :) Corinna -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Maintainer cygwin AT cygwin DOT com Red Hat
