PHP 4.0 Bug #7505 Updated: ldap_get_entries causes crash

ID: 7505 User Update by: weston@itdonline.net Status: Feedback Bug Type: LDAP related Description: ldap_get_entries causes crash I'm not quite sure how to go about getting a correct backtrace, but I believe that the problem is occurring in getattr.c from OpenLDAP-2.0.6. It looks like this: assert( LDAP_VALID( ld ) ); For some reason, this assert fails and causes the Apache process to exit. It may not be the correct thing to do, but I commented out that line and recompiled OpenLDAP. After I did that, everything works again. I didn't figure it would make a huge difference, since LDAP_VALID expands to a comparison of ld->ld_options.ldo_valid with the constant, LDAP_VALID_SESSION (0x2). I'm guessing that somewhere along the line, this flag isn't being set properly.
