>Description:
While compiling OpenLDAP 2.1.12 (http://www.OpenLDAP.org)
gcc 3.2 is making broken one small peace of code. I have reported bug on openldap-bugs list and OpenLDAP developer
told me that this look like optimization bug uin gcc 3.2

The mentioned code is in penldap-2.1.12/libldap/liblunicode.
gcc is making help tool "ucgendat" which is producing unicode ".dat" files for use by libldap library, slapd(8) daemon, slapindex(8) and slapadd(8).

If I use -O3 -O2 or -O (as for the rest of OpenLDAP code)
ucgendat will produce broken unicode tables in dat files.
As a consequence mentioned programs will segfault while
indexing LDAP attributes which have UTF-8 non/ascii letters
in their values.

After recompiling ucgendat without optimization and making
dat files with *that* ucgendat, everything seems to be OK.
>How-To-Repeat:
Compile OpenLDAP on SunOS 5.8, with `-m64 -O3 -mcpu=ultrasparc"

install it, make a small LDAP database, put non-ascii values in cn or sn attribute, write

"index           cn,sn,uid   pres,eq,approx,sub"

in slapd.conf(5) after database definition and run slapindex(8)
tool.
>Fix:
Dunno, For now, I compile unicode dat files again after
optimized OpenLDAP build as a workaround.
