3573.0. "SERVER Crashes after XSetFontPath" by RICKS::AKHIANI () Thu Nov 01 1990 19:08

 Long time ago I wrote a program that install fonts on my server.
 all it does is a call to:
	 XGetFontPath
 to get current Font path and then add a new path to it and then:
	 XSetFontPath

 It does a good job,(you don't have to ask the system manager to 
 install fonts for you).

 However, there is a side effect.
 As long as you use the Session Manager Session-->Pause option  
 everything is fine, but if you quit the SERVER crashes.

 CRASH DESCRIPTION:
 After I do Session Manager Session-->Quit screen freezes and If I 
 touch any key screen blanks and the workstation screen look like a
 terminal. and DECW$SERVER_0 process that should be running is not 
 present when I do $SHOW SYS

 I have a VS3100/SPX, VMS 5.3 and no idea how to get the version of
 DecWindows. This problem is reproducable and it also happens on 
 MICROVAX II/GPX.  

 This program runs in the user mode and crashes the server. This is
 serious Bug since User Mode programs should not be able to crash a machine.

 I can post my program and the complete Server Log if somebody wants it.

All obvious bugs like server crashes should be QARed.  See note 2
for information on how to enter a QAR.  Please supply the program
source and the complete server log.

By the way, if the server crashed, there should have been a stack
dump at the end of the server log.  Did the log really end with no
stack dump?
