RE: slapcat segfaults loading BDB (ITS#2974)

Does this help?  I'm not sure on the usage of Electric Fence... I think I got it to do something useful.

(gdb) run -f /home/armbrust/foo/schemaicd9.conf -l /home/ldap/source/icd9/icd9.out.ldif

Since the crash is in malloc, there is likely a memory corruption bug somewhere.
If you can link the slapadd binary with a debugging malloc library (like
ElectricFence) and run the program under gdb, that will probably pinpoint the
error.
