I was hoping you wouldn't say that ;->
I will look at it some more. I spent many hours looking at tty.cc,
fhandler_termios.cc, dtable.cc, and related code over the weekend, and
got wound around the axle trying to figure out where the pgid of the
tty was getting set. I couldn't get the watch point to tell me when/where
it was getting changed. And as you know printf is problematic during the
early startup sections where it's setting up the tty itself.
You're right, t->getpgid() should be 0 for a process with a pipe for stdin.
There's definitely a bug lurking in there somewhere.
Will let you know what I find out.
BTW, do you want me to jump over to the cygwin developer list?
I just don't want to annoy folks with the traffic if this is not
the appropriate place to get feedback for this type of a debugging
exercise.
And thanks for your patience. This is my first "dive" into the internals
of the cygwin DLL code.

You're still fixing the symptom rather than the problem.
If the program doesn't have a controlling tty then t->getpgid should be
zero. If it isn't zero, then I want to know why it isn't zero.

No, I didn't know that. It's difficult to understand why anyone would
do something that dumb. If they do, they get what they paid for.
Or, rather, I guess I'll get what they paid for because then they'll
send email whining about cygwin instabilities.
