I can confirm this behavior for rxvt on Win2k, and have some more info: rxvt only crashes in W11 (Windows native) mode, in X11 mode it works fine. I've run strace, and the output is quite interesting. rxvt apparently goes into an infinite loop trying to setup a signal handler, and runs out of stack space. I've attached strace output (with only the first few frames of the infinite loop).
I also have another problem. Apparently, 'ssh -X' hangs when requesting a
pty. This doesn't happen if the -X flag is not specified, but does happen
with the -X flag in both SSH1 and SSH2 modes. I've attached the output
of 'ssh -v -X -1 [EMAIL PROTECTED]' and 'ssh -v -X -2
[EMAIL PROTECTED]'.
