DDD 3.2.1 (i686-pc-linux-gnu) gets `Segmentation fault' signal

[xucaen]

While debugging some source for a data structures class, DDD abended with the 
Following messages. Since I do not know how it happened, and it does happen 
every time,
I am attaching the source I was trying to debug. Each source was compiled
with g++ 1:2.95.2-13 on Debian GNU Linux 2.2r3, linux kernal 2.18pre21 (please 
forgive
if I have the kernal version numbers wrong)
