Yes!  I discovered, however, that I could make the problem go away by
selecting the "Watch Progress" choice on the Options Menu.  According to
the dxpsview man page:

	Usually, dxpsview prepares and stores an entire
	page in its cache before drawing it. With the
	Watch Progress option on, dxpsview displays images
	immediately as it prepares them.  

So it sounds like they've got a serious bug in a call to
malloc (or XMalloc) somewhere, and selecting this item merely
avoids (as opposed to fixes) it.

Amusingly, it was our DEC rep and a software consultant he'd brought
along who first demonstrated dxpsview (or attempted to) to me after our
workstation (DECstation 5000/200 running 4.0) had been installed.  The
software consultant who was familiar with dxpsview was clearly taken
aback by the BadAlloc bug.

Other than that, by the way, I'm pretty impressed with dxpsview.
I don't have a lot of PostScript viewers under my belt, but
it's the nicest one I've seen.  The only feature I wish it
had was some better debugging facilities (in particular, pstack).

Incidentally, if anyone can give the proper Xresources incantation to
set the 'Watch Progress' option from the .Xdefaults file, I'd be much
obliged.  The man page is a little thin on detail.

>How about "dxpsview" under Ultrix 4.1? 

Don't know.
