It moves things around in this array and eliminates the NULL termination. The Cygwin DLL should not crash when a user changes input like this, (and this is the second problem we've seen like this in two weeks) but still, what tee is doing is very strange. cgf -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

FWIW, I was able to reproduce your problem (in fact, simply calling /bin/procps -p $$ -o 'pid,ppid' | tee test.out was enough to trigger the problem). At the moment, I don't have an unstripped version of the DLL installed on my system, so I couldn't do the debugging necessary for this. From the range of addresses in the stack trace, it seems to happen somewhere in the Cygwin DLL itself. I've compared the strace for the problematic command with the one from simply doing echo | tee test.out. The difference in straces is not significant (to me), except that readv() seems to never get to the end of fhandler_base::read(). I'm attaching the relevant chunk of the diffs (with times and PIDs stripped out to minimize noise) in the hopes that this helps someone else debug this.
