Subject: Re: tty initialization failure under cygwin 1.7.2?

I ran across this same problem today on Server 2008 with
1.7.3(0.225/5/3) and may have some info to help reproduce this issue.
I get this error using:

$ cmd /c "bash -c ls"
      7 [main] bash 3336 C:\bin\bash.exe: *** fatal error - couldn't
initialize fd 0 for /dev/tty2

with an ssh session and a non administrators account.    If I use RDP or
an administrative account, it works fine.    While the example probably
seems a bit bizarre, it's actually something you would run into if you
used backticks with ActiveState Perl to execute a Cygwin command.

I'm wondering if that's a side effect with some other software.  I can
not reproduce your problem.  I tried your test scenario and it works for
me.  I don't get any weird error from ls.
