Actually, after doing a straight configure, I saw that CFLAGS and 
CXXFLAGS were both set to:
-g -O2
so I doubt that it strips the symbols (what would be the point then of 
the -g?). I get the same crash whether I compile pan myself or use the 
pre-built SUSE 10.1 pan 0.99 binary (pointed to from the pan web site). 
I do NOT get the crash when I use a different news server. So it is 
something in the newsgroup list of this particular server 
(newsgroups.comcast.net, actually giganews) which is triggering the bug. 
Now if only I could figure out what the offending group name is, maybe I 
could come up with a patch, or at least a useful bug report.
