Oh, so do I need to build everything unstripped? That would be difficult
when using the ports.

From the ports!

I do believe this problem is something to do with the OS version on 
which it is happening, and perhaps might be so difficult to get round
to solving. All this is happening on FreeBSD 4.11, with MySQL-4.0.27.
This system could be "dirty" - some stale libscould be lying around!

I have simulated a similar setup on FreeBSD 5.5 and 6.2 both using
MySQL-4.1.22, and FreeBSD 7.x using MySQL-5.0.41 and there is no
crash at all. I create a file hierarchy for the mail_location and
everything seems to work perfectly.

The only problem I am facing is that the actual mail_store that I
need to move to another server via imapsync does live on the
FreeBSD 4.11 box!

It would be nice to get to solve this problem, as that would make
life easy for me, but now I am beginning to think that I could as
well rsync the data onto another machine and access it from there.
NFS-mounting the mail store would be another option but I hate to
deal with NFS-related problems too:-)

| I meant just "gdb attach 11447". Except not 11447 but the "dovecot-auth
| -w" process. Apparently it hasn't been started yet. You could do a login

Ok. Allow me to understand this, even if just for another day..

The login fails with an error, of course.

Now, what am I supposed to type/do on the gdb shell?
As you can see, it has the word "Continuing"... anything I need to type 
to get it our of that so that it again accepts my commands?
