Summary: Set a new user password...
Initial Comment:
I created a new user:
CREATE USER "voc" WITH PASSWORD 'voc' NAME 'VOC_EXPLORER' SCHEMA "sys";
CREATE SCHEMA "voc" AUTHORIZATION "voc";
ALTER USER "voc" SET SCHEMA "voc";
I alter the password user:
alter user "voc" with password 'new';
And then I start a mclient:
/mclient -lsql -uvoc
Password:new
the mserver crashes:
>mserver5: /ufs/goncalve/MonetDB/MonetDB5/src/mal/mal_authorize.mx:328:
>AUTHcheckCredentials: Assertion `q != 9223372036854775807LL' failed.

We used BUNinplace(b, p, BUNhead(), v, FALSE). In these cases BUNinplace
can fall back to delete/insert, which means that the value to which BUNhead
points could change. Now we use local variables instead.
A test should still be added.

Well, the problem is back if I restart the Mserver.
I will not commit the changes and I will leave this bug open.

problems here are:
1) I couldn't reproduce
2) Niels and I got stuck last year after finding that BUNinplace simply
did the insert, but the insert finally got lost on a restart.
Debugging/fixing 2) is way beyond my expertise, time limitations and
aspirations.

This crash is gone.
I ask to the God father of the authorization model if he aggrees with this
change?
If yes I will check in, create and approve test, and close the bug.
