I still have problems with libnss-ldap and the lastest version of
libldap2 doesn't seem to solve it :
when I use wml (which is basically a perl script but sorry, I can't
actually narrow the bug to a perl script), here is what I got :
$ wml -o 1.html 1.wml
** WML:Break: Error in Pass 2 (status=139, rc=0).
then, here is the core backtrace :

...so I tried to recompile libnss-ldap version 238-1 linking with ldap_r
but it didn't work either
so I went back to libnss-ldap version 220-1 (which dates back to August
2004) and everything went fine again !
it could help me to report the bug in debian (weither it is a bug
related to amd64 or not, this is yet another question...)
I don't know how to trigger the bug in Perl (it really seems perl is the
culprit here)
any idea ?
