problem: tex omits every other word in wrapped lines

We have just installed TeX, Version 3.1415 (C version 6.1).  We are
running SunOS 4.1.3u1.  Everything is fine, except that in paragraphs
in which words are wrapped, the wrapped lines have every other word
omitted.  The space is there for the word, but the text itself is
missing.  For example:

How it should look:

This is a test paragraph.  This sentence will wrap and will be missing
words.  This sentence will be ok.

How is really looks:

This    a      paragraph.       sentence      wrap     will    missing
words.  This sentence will be ok.

Using dvitype, we have determined that an overflow is occuring (it
says so)....we had no problems compiling, so we have no clue where to
start looking for the problem.  

Here's how dvitype should look after the first word of the paragraph:

166: push
level 1:(h=0,v=1441792,w=0,x=0,y=786432,z=0,hh=0,vv=91)
167: right3 1310720 h:=0+1310720=1310720, hh:=83
171: setchar84 h:=1310720+473316=1784036, hh:=113
172: setchar104 h:=1784036+364090=2148126, hh:=136
173: setchar105 h:=2148126+182045=2330171, hh:=148
174: setchar115 h:=2330171+258503=2588674, hh:=164
175: w3 197495 h:=2588674+197495=2786169, hh:=176
179: setchar115 h:=2786169+258503=3044672, hh:=192

182: setchar117 h:=3736443+364090=4100533, hh:=259
183: setchar108 h:=4100533+182045=4282578, hh:=271
184: setchar100 h:=4282578+364090=4646668, hh:=294
185: w0 197495 h:=4646668+197495=4844163, hh:=307
186: setchar98 h:=4844163+364090=5208253, hh:=330
187: right2 18205 h:=5208253+18205=5226458, hh:=331

How it really looks (using the old version of dvitype):

166: push
level 1:(h=0,v=1441792,w=0,x=0,y=786432,z=0,hh=0,vv=91)

172: setchar104 h:=1784036+364090=2148126, hh:=136
173: setchar105 h:=2148126+182045=2330171, hh:=148
174: setchar115 h:=2330171+258503=2588674, hh:=164
175: w4 -2147265195 h:=2588674-2147265195=-2144676521, hh:=-135845

184: setchar108 h:=-2143362157+182045=-2143180112, hh:=-135750
185: setchar100 h:=-2143180112+364090=-2142816022, hh:=-135727
186: w0 -2147265195 arithmetic overflow! parameter changed from
-2147265195 to -4667625 h:=-2142816022-4667625=-2147483647,

187: setchar98 h:=-2147483647+364090=-2147119557, hh:=-135998

I don't really know what these numbers mean, but the h: things
continue to be negative, yet words still keep appearing.  They return
to normal for the second sentence of the paragraph (which didn't
wrap).  Also, using the new dvitype, the hh: numbers alternate between
0 and -2147483648 throughout the entire file, and once the numbers get
screwed up, they remain so, even for the text that shows up correctly.

Any help at all is greatly appreciated.

Thanks!
