Hi Dave,
I've tried to reproduce the problem on a different computer without
success. So, the problem appears to be specific to this particular
machine.
Are there any characteristics of my machine that could influence bash's
ability to fork/exec processes? How can I further diagnose this
problem?
Thanks to all of you that informed me about alternatives to cat;
unfortunately, the problem crops up with other programs (wc is the one
I'm actually using), so avoiding cat doesn't solve my problem. In any
case, it's pretty weird that bash randomly fails to spawn child
processes! It wreaks havoc on a number of my scripts.
Regards,
Russell

Yep, I tried

before I thought about modifying it. Didn't get the error to occur.
Will run
it a few more times and see. Am using self-built version of cygwin1.dll
from
20060720. I'll see what happens with a more recent version as well.
cheers,
