Do you get an error message when it crashes?

Yes:

** (emacs:3752): WARNING **: Couldn't connect to accessibility bus:
Failed to connect to socket /tmp/dbus-idEV6pXtAp: No such file or
directory

This warning is normal (and harmless) when you login remotely.

 > (... some seconds wait ...)
 > Fatal error 12: Bad system call
Bad system call         (core dumped) emacs

The second message is sometimes omitted, however.



Does it leave a stackdump file?

Yes:

Have you enabled X11 forwarding in /etc/sshd_config?

Xterm works, so I guess I did.

It wouldn't hurt to double check; you should have a line that says 
"X11Forwarding yes" in /etc/sshd_config in the Cygwin installation.

Also "emacs -nw" works.

This doesn't use X.



Please provide as many details as possible

The box from which I ssh into this runs FreeBSD... I'm using a domain
user... X runs fine locally...
Sorry, I really don't know what else to add.

I'm willing to play any test you need, but I don't always have this box
avaliable, so it might take time.



and please attach cygcheck output as requested here:

Please, find it attached.

It looks like you don't have the cygserver service running.  My 
recollection is that you might need this for X11 forwarding of emacs to 
work.
