>Description:
	A certain valid Postscript file that I have in my possession is repeatedly causing
	ghostview to crash with a coredump at startup.  (I know the file is completely valid
	because when I just simply `cat' it to /def/ulpt0 it prints out beautifully and with
	no problems.)

	I'll provide the file upon request, but I would prefer not to publish it widely.

	The file in question is nothing special.  It was generated from a .pdf file by pdf2ps
	and it is just a three page business document.  No graphics, no multimedia, nothin'
	fancy.  Just straight text.

>How-To-Repeat:
	Run ghostscript on this file I have here (available upon request).

>Fix:
	I don't have any idea even how to debug this.  I did try compiling ghostscript with
	make -DWITH_DEBUG="yes" (as suggested in some places) and that allows me to get at
	least a stack traceback after the coredump, but gdb still isn't letting me do the
	"list" command (and I'm not even sure why) so I can't even find out which source line
	ghostview is crashing on.

	Here is the stack backtrace:

	(gdb) where
	#0  0x0000000000410fe7 in psscan ()
	#1  0x0000000000408687 in setup_ghostview ()
	#2  0x0000000000405d2a in main ()
	(gdb) 

	Should I be filing a bug report on GDB also?  I mean, you know, since the "list" command
	doesn't seem to work?
