Segmentation fault after xdm login

- Subject: Segmentation fault after xdm login
- Reply-to: cygwin-xfree at cygwin dot com
My first attempt at the xdm login screen causes Xwin(debug version or
not) instantly reappear with the same xdm login and the second attempt
results in a segmentation fault. The remote box is a Redhat 9. In the
xdm-errors file I can't see any messages at all even after increasing
the "DisplayManager.debugLevel" parameter located in
"/etc/X11/xdm/xdm-config".
All the following output belongs to an "XWin-Test101-DEBUG.exe" session.
Thanks a lot,
Cem Han
