I finally got a closer look at it and found interesting thing. Chris, you said, you use Zsh. I hope, you won't mind to compile it - it does it OOTB. The following happens with current Zsh CVS; it may happen with 3.1.9-dev-6 (the last released version) as well, but I have not tested it. cygwin-20001014 snapshot. Look at http://www.zsh.org or http://sourceforge.net/projects/zsh for Zsh sources. Compile Zsh; no special configure options are needed; I use --prefix=/usr. Run it; I use direct shortcut to zsh and put path=(/usr/bin /usr/local/bin $path) in /etc/zshrc. You may even run it as 'c:\cygwin\bin -f' to get clean state. Then execute: MW1G17C% zmodload zsh/zpty MW1G17C% zpty zsh zsh -f MW1G17C% zpty -d zsh 0 [main] zsh 1868 close_handle: attempt to close protected handle int proc_subproc (long unsigned int, long unsigned int):289(childhProc<0x180>) 2567 [main] zsh 1868 close_handle: by int fhandler_pty_master::close ():912(get_ttyp ()->to_slave<0x180>) MW1G17C% To comment: zpty allocates pseudo-tty and starts command attached to this pty. It assigns it handle `zsh'. zpty -d tries to kill associated command by sending it HUP. I CANNOT reproduce it with strace. Simply starting 'strace -ozsh.strace zsh -f' hangs forever. If you may point to a bug in zsh that causes it - you are welcome. In the following cygcheck cygwin1.dll is listed twice - because I started zsh via run and cwd was c:\cygwin\bin All this does not happen with stock 1.1.4. It did not happen in at least some post-1.1.4 code (I specifically tested it to see if pty bug was fixed). It may or may not be related to bash exiting problem. -andrej Have a nice DOS!
