Brian,
Thank you for your reply.
But I can't get the point so much...

---- I think that usually cygwin automatically makes the directory
assigned as the default home in nsswitch.conf (and indeed it does).
I tried the same experiment with making C:\Users\test\cygwin manually
before launching cygwin,
but the same crash is reproduced.

---- Well, I know that I want to assign the home directory
automatically to every user of my lab.
I don't know the internal structure of cygwin and so what I can do is
to only announce
"Do not use cygwin at your very first sign-in to the machine.
Re-sign-in before launching cygwin".
But I think this is a bit ridiculous...

---- Actually, in my experiment, cygwin does make the directory
C:\Users\test\cygwin
and even I could output cygcheck to C:\Users\test\cygwin\foo.out (or
/cygdrive/c/test/foo.out).
The problem is only in the crash of the window system.
Addendum:
Setting Windows environment variable HOME to be /cygdrive/c/users/test
works without the issue,
but it does affect another application in my lab as documented in
cygwin's users guide.
Yours,
Yuta Suzuki
