Some days ago I updated the cygwin system by 'setup.exe', expecting
some "GL" problems are fixed. Since then XWin crashes with some
application programs. One of the most simplest is 'xlogo'.
What I have done is as follows;
Start [XWin Server] (wait some time for bringing up xterm), then enter
'xlogo' in xterm, [Cygwin/X] window appears immediately. It says,
> A fatal error ...
> Caught signal 11 (Segmentation fault). ...
> Please open /var/log/xwin/XWin.0.log ...

> X :0 -multiwindow
/var/log/xwin/XWin.0.log does not report anything important at all.
OK, I tried 'X :0 -multiwindow' on one terminal, and on the other
$ export DISPLAY=:0.0
then, the message appears on one therminal;
>Segmentation fault at address 0x44
>Fatal server error:
>Caught signal 11 (Segmentation fault). Server aborting
>Server terminated with error (1). Closing log file.
>winDeinitMultiWindowWM - Noting shutdown in progress
>winMsgWindowProc - pthread_mutex_unlock () failed: 1
while entering 'X :0' on one terminal, entring 'xlogo' on the other,
there was no fatal problem. Obviously '-multiwindow' does something
Keith Lindsay's post might be helpfull as workaround, but I cannot
rollback to the 'version 1.12.0-1 of xorg-server (built 2012-03-12)'
