1.14.0-2 XWin does not start, though 1.13.2.0 X Server latest snapshot 20130210-git works

[Vasiliy <testtest_2005 at ukr dot net>]

- 1.14.0-2 XWin X Server installation is broken after replacing 1.13
in Cygwin (1.17.18 / 1.17.19s)
- no software interfering with Cygwin is installed
- reinstalling xorg-server doesn't help
- with the latest Cygwin snapshot (20130503) it might cause 1.14.0-2
XWin core dump

[.xserverrc]
XWin -multiwindow -wgl

'Symptoms' (irrelevant to the content of ~/.xserverrc):

1.17.18:
xinit: giving up
xinit: unable to connect to X server: Connection refused
xinit: unexpected signal 2

1.17.19s:
~/.xserverrc: line 1: #### Aborted (core dumped) XWin -multiwindow -wgl
xinit: giving up
xinit: unable to connect to X server: Connection refused
xinit: server error

Specifics (notice no problem with 1.13 XWin, and less with the OpenGL driver):
GL_RENDERER:    NV31GLM Pro/AGP/SSE2 (NvStrap'ped GeForce FX Go5600)

XWin-backtrace.log contains:
1.17.18-backtrace
1.17.19s-backtrace (XWin.0.log)

XWin.1.log (1.13 run without .xserverrc):
normal run, equivalent to -rootless -nowgl

XWin.2.log (1.13 run with -multiwindow):
good run, but no autostart of applications from /etc/X11/xinit/xinitrc
then 'waiting for X server to begin accepting connections'.. .. ..
one can run/close xterm, however, dry exit from the X Server causes (why?):
xinit: giving up
xinit: unable to connect to X server: Connection refused
xinit: server error

XWin.3.log (1.13 run with -multiwindow -nowgl):
perfectly normal run, autostart of applications from /etc/X11/xinit/xinitrc

XWin.4.log (1.13 run with -rootless -nowgl):
normal run

Expected:
1.14.0-2 XWin working

Best regards,
Vasiliy
