Interestingly enough, I got the same result as you on an initial compile/run 
of slapd. Unfortunately, with optimization, the backtrace wasn't all that 
useful. Recompiling back-mdb with just -g, no optimization, gets a different 
result though - slapd is fine, and ldclt dies with a heap corruption or 
double-free.

ldclt -h localhost -p 9011 -D cn=manager,dc=example,dc=com -w secret -b 
ou=people,dc=example,dc=com -e 
object=xx.txt,rdn='uid:[A=INCRNNOLOOP(200000;999999;6)]' -e add,commoncounter 
-I 68

All subsequent runs give the same result. Still looking into this; getting 
away from the Ubuntu bundled libldap will probably help.
