The following expression causes Emacs to crash in Windows 7 (and
probably other versions) with Emacs 24.3.1:
(with-temp-buffer
(start-process "crash-emacs-bug" (current-buffer) nil)
(process-send-eof))
The `start-process' call here is creating a pty process (according to
the docstring). The exact version string is (official GNU build):
GNU Emacs 24.3.1 (i386-mingw-nt6.1.7601) of 2013-03-17 on MARVIN

PTYs are not supported on MS-Windows. I added some protection so that
Emacs doesn't crash (trunk revision 115538), but I doubt if Emacs will
do anything useful when start-process is called that way on Windows.

I don't use skeeto, so I have no idea what it tries to do in this
case. So I cannot offer any advice for how to make skeeto work on
Windows in this case, nor tell if that is even possible.

Closing, as I don't see any reason to leave this open. OP reported a
crash scenario which was fixed; ptys can't be implemented on Windows
because Windows doesn't provide support for such a thing.
