1.9.2.0: Xwin SIGSEGV when font server should be queried
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.

AW: 1.9.2.0: Xwin SIGSEGV when font server should be queried
The previous version, that was stable for xorg-server was 1.8.2-1, according to setup.log. The gdb stack trace is not very talkative: ... Loaded symbols for /usr/bin/cygXrender-1.dll [Switching to thread 8788.0x2740] (gdb) c Continuing. (no debugging symbols found) Program received signal SIGSEGV, Segmentation fault.

Something funny about it: I had the xset fp+ tcp/mystique:7100 commented out in the .startxwinrc. Then I started XWin, attached the gdb and issued the xset command from within a AIX aixterm shell. Then I started a window that has to use a font server font and it worked. Then I activated the xset command in the .startxwinrc again and the XWin crashed again. I keep on researching.

AW: 1.9.2.0: Xwin SIGSEGV when font server should be queried
I did a bit of further reseach.
It looks like it does not have anything to do with the way the font server is
queried,
but rather the way the startup is done.
When I have the font server added during the XWin startup - either in the
startxwin.bat, or a bash-script I call from there, the XWin SIGSEGVs.
When I let the XWin come up with a few of my fav screens, and I then add the
font server either from a cygwin shell or from a client shell the font server
is subsequently queried correctly and the SIGSEGV does not appear.
Strange.
Anyway.
Thanks for the exe to create a full stack trace.
Here it is:

AW: AW: 1.9.2.0: Xwin SIGSEGV when font server should be queried
I managed to work around it. In the startup of XWin I start a few windows. In one of them I add the font server after a bit of sleep to settle down XWin. Now the XWin does not SIGSEGV any more why so ever. Here are the scripts I use to start up my X environment Burkhard Startxwin.bat: @echo off SET DISPLAY=127.0.0.1:0.0 REM REM The path in the CYGWIN_ROOT environment variable assignment assume REM that Cygwin is installed in a directory called 'cygwin' in the root REM directory of the current drive.

REM REM This batch file will almost always be run from the same drive (and REM directory) as the drive that contains Cygwin/X, therefore you will REM not need to add a drive letter to CYGWIN_ROOT.
