   I just grabbed the comp.sources.unix Postscript previewer (the one by
Crispin Goswell).  I applied the changes made by John Myers of CMU; the
change specified by Steve Beaty (beaty@handle.colostate.edu) did not seem
necessary, as it looked to me like there was a non-pixrect-specific change
already in place to take care of his bug.  Other than that, I have made no
modifications to the program.

   When I feed a Postscript file to sunPS, sunPS exits without dumping core,
but without drawing anything, either.  When I use xps, I get a core dump
in BitBlt, when xps dereferences a null pointer.  If I compile xps on a
VAX running 4.3BSD, and tell it to scribble on my Sun display, I get:

	X Protocol error:  BadDrawable, invalid Pixmap or Window parameter
	  Major opcode of failed request:  62 (X_CopyArea)
	  Minor opcode of failed request:  0
	  Resource id in failed request:  0x4a110f00
	  Serial number of failed request:  90
	  Current serial number in output stream:  167

   I get similar results when I tell xps to scribble on a QDSS.

   I'm using what ptroff produces when run on the 'tee' man entry as a test.
The Postscript produced prints fine on LaserWriters of various flavors.
I'm running 4.3BSD-tahoe (more and less) on the VAXen involved, and I'm
running SunOS 3.2 (with the 3.5 SunPro compilers, and with local hacks) on
my monochrome Sun-3/60.  All the machines involved are using X11R3, with
patches 1-7 applied.

   Before I try to find the time to go digging, has anyone had similar
problems, and has anyone figured out how to fix them?
