1.9.2.0: Xwin SIGSEGV when font server should be queried

["Weeber, Burkhard" <b dot weeber at viastore dot com>]

Hello,

I updated my Cygwin with the latest available from the "setup.exe".
Now XWin.exe gets a Signal 11 (Segmentation violation) when a font switch (-fn) is on the command line.

Command:
$ ssh -Y myaix "aixterm -fullcursor -geometry 81x30-125+93 -e /usr/local/bin/max.pl"
Is OK.

$ ssh -Y myaix "aixterm -fullcursor -geometry 81x30-125+93 -fn 6x10 -e /usr/local/bin/max.pl"
Fails.

I have a font server running on AIX6.1 and before the start this font server is added by xset command.
This worked well until the update.

Also the xlsfonts command of cygwin distribution causes XWin to SIGSEGV.

Also when specifying "-fp tcp/myfontserver:7100" on the XWin start line any X-Program will cause a SIGSEGV.

Regards

Burkhard
