Here's more information.  After having to do some makefile surgery to 
change "-g -O2" to "-g" do I could actually debug (--enable-debug 
notwithstanding), I got the following out of gdb:

(gdb) run -s -f -x=5 -y -z
Starting program: /usr/local/sbin/radiusd -s -f -x=5 -y -z

Program received signal SIGSEGV, Segmentation fault.

I went directly to mysql and ran the query that sql_cache_retrieve 
doesn't seem to like:

mysql> SELECT attr,value FROM attrib_pws WHERE user_name='ggersh' AND op 
IS NULL;
+----------------+---------------------------------+
| attr           | value                           |

+----------------+---------------------------------+
4 rows in set (0.01 sec)

So, there's still something busted here.  Is there anything else I can 
give to help debug this?

Thanks.
