Some Problems with 2.1.3 (and HEAD) on 64bit archs

[Ralf Haferkamp <rhafer@suse.de>]

Hi,

After some small changes to liblunicode (see ITS#1960), I was able to build
2.1.3 on Linux on various 64bit arch (including ia64, ppc64 and s390x aka
z-Series).  The server seems to work well, though I haven't had the chance
to test enough.

But now I have some trouble with the client side (it seems to work on ia64
though). Sometimes when I issue a query using ldapsearch the client just
hangs in a call to read() and never comes back again.

This however happens only after the last result attribute of the search was
returned. (strange, isn't it?)

Attached you will find a backtrace of the client process. (generated on a
s390x running SuSE Linux 7.2)

Do you have any hints what I can to fix this problem?

BTW: It doesn't make a difference what OpenLDAP version is running on the
server side, it reproducable with 2.0.23 and 2.1.3.
