This is a known problem under CDE.  The front end is having trouble with
the default fonts (dt foundry) of CDE, and this leads to a seg fault.

You can fix the problem by overriding the font selection with the
following X resource:

XMathematica*fontList: <some font here>

where the font name follows the X logical font description convention:

http://www.it.umd.edu/unix.help/Utilities/X-windows/XFont_Fields.html 

The resource line should be added to your .Xdefaults file in your home
directory.  If this file doesn't exist, create a new file by this name
with the above line it it.

I use Helvetica-Medim 12 pt in my work, so the resource setting I use
is:

XMathematica*fontList:
-adobe-helvetica-medium-r-normal--*-120-*-*-*-*-*-*

However, any font available on your X server will suffice.  You can get
a list of the fonts by issuing the command:

	xlsfonts | more

in a shell on your Digital Unix machine.
