Bug Type: Sybase (dblib) related
Operating System: FEDORA CORE 7
PHP Version: 5CVS-2007-09-12 (snap)
New Comment:
Did you have same sybase libs in the other system too?
It seems to me that there's simply a conflict between openldap and
sybase's own ldap implementation and there's not much we can do about
that..

Note that to have ldap support sybase client shuld be 12.5.1 or 15.
I made test with Sybase OpenClient 15
The same configuration ( enable ldap and sybase ) with php 5.1.6 and
fedora core 5 works

Description:
PHP sybase_conect Crash when compiled with with-sybase and with-ldap
and sybase name resolution is done via LDAP
If PHP is compiled without ldap extension all works.
If Sybase resolution is done via interface file and not via LDAP all
works
To reproduce :
1) Compile php with :
./configure --enable-debug
--with-sybase=/sbrdbms/sybase/OpenClient15/OCS-15_0/ --with-ldap
Enable ldap sybase resolution by uncomment the following line in
$SYBASE/$SYBASE_OCS/config/libctl.cfg
ldap=libdldap.so ldap://ldaphost/dc=sybase,dc=com
Please note that in this example the ldap server is only the default
example. In this situation the sybase_connect should return error
instead of a stack trace
2) Run the following simple php script
?php
$my_server='DBA_SUN_TEST' ;
$passwd='xx';
$login='sa';
$db=sybase_connect($my_server,$login, $passwd) ;
sybase_close($db);
?

Please note that in this example the ldap server is only the default

(because it don't find the ldap server correct configuration) instead of
a stack trace
2) Run the following simple php script
?php
$my_server='DBA_SUN_TEST' ;
$passwd='xx';
$login='sa';
$db=sybase_connect($my_server,$login, $passwd) ;
sybase_close($db);
?
Expected result:
an error or a sucessfull connection
Actual result:
--
A segmentation fault .
