I cloned the git repository "git://git.openldap.org/openldap.git", then I
compiled this version "2.X" as specified in the 1st message.
Please consider that, after recompiling this version, I rebooted the server
where slapd is running.
As far as I can see, it seems the memory consumption is the same as 2.4.42:
it starts to increase up to 60%.
In fact, with gdb, I got now an assertion failed due to:

So, a malloc failed returning NULL.
This happens also with the 2.4.42.
Now I relaunch again the loading procedure and see what's happening.
