I use ditroff to format documents for an Interpress (Xerox 8044) printer.
This has been working successfully for over a year, using the dipress post-
processor which came with Release 1 of the Interpress Toolkit from the Xerox
Systems Institute. However, I recently upgraded to 4.3BSD and want to use the
new version of dipress which came with it, but I've been having problems.
(I've actually also encountered identical problems with XSI's Interpress
Toolkit release 2.1).

Ditroff runs fine, but runing dipress produces errors like this (I've editted
them to fit in 80 columns):

(eusip)1% bin/dipress -f lib/fonts/8044 -t simple.dit > simple.ip

bin/dipress     Memory fault - core dumped
(eusip)2%

When dipress dumps the core, it's in this state:

 _malloc(1c) from 56a
 _setFontPosition(4,d50b,d515) from 20d
 _readDeviceInitInfo() from _deviceCommand+48
 _deviceCommand(956c) from 972
 _ditroffToIpress(956c) from 1543
 _main(5,7fffea44,7fffea5c) from start+3d

Does anyone have any ideas about how I can fix this?
