Re: XWIN-1.11.3.0 crashes when some client programs terminate.

Sat, 21 Jan 2012 16:44:02 -0800 

Hi folks.
I was on vacation so I couldn't replay.  3 days ago I tried to reproduce the 
crash,
but it did not happen!  I have not installed new software since the previous 
crash,
 niether cygwin nor Windows.  I do not understand how that can be. The only
difference I can think of is that when the crashes happened 2 weeks ago I had 
ben working
for a long time with the machine. Three days ago I just booted the machine and 
tried to
reproduce the crash.  Today I tried again and the crash was back again (my wife 
had been
using the machine all day). I have made the backtrace as suggested. It is 
attached 
together with the XWin.0.log.
In order to have the crash you have to interact for a while with the test 
program
and then close the window. 

About the locale non working, I start the X server with a windows batch script 
that makes
the following sets before running XWin:

SET DISPLAY=127.0.0.1:0.0

SET XAPPLRESDIR=/etc/X11/app-defaults
SET XCMSDB=/usr/lib/X11/Xcms.txt
SET XKEYSYMDB=/usr/share/X11/XKeysymDB
SET XNLSPATH=/usr/share/X11/locale
SET XLIB_SKIP_ARGB_VISUALS=1
SET LC_ALL=es_VEN.ISO-8859-1

Hope that this can be useful
