I assumed it was just me, as I have an old-ish self-compiled bash in a highly nonstandard environment. I have the symlink, but my process-substitution-happy shell scripts started breaking this way, recently, as well. Mine die, suggestively, at /dev/fd/63. They don't /always/ all die; but somehow, I crossed some kind of rubicon and now they do all die. If I carefully smell the air afterwards there is the faint odor of scarce OS resources leaking. (Just kidding about that last part :P) Haven't been able to clear out the process table or generally to "get all diagnostic" on it yet; it's on my list but I really must finish some paperwork for a certain government agency. I'll get back to the list with whatever I can figure out about this sometime soon. -gmt -- 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
