Reeeeeely! 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.
