I installed debugging symbols and got a full backtrace. The top stack frame is #0 uldap_connection_init (r=0xb715d830, ldc=0xb7f086e0) at /usr/src/debug/httpd-2.2.10/modules/ldap/util_ldap.c:261 rc = <value optimized out> ldap_option = 0 version = 3 result = (apr_ldap_err_t *) 0x0 timeOut = {tv_sec = 10, tv_usec = 0} The source code for this location can be seen at <https://svn.apache.org/repos/asf/httpd/httpd/tags/2.2.10/modules/ ldap/util_ldap.c>. The bug is that it doesn't check whether 'result' is null. And I can also see that happily, a null-pointer test was added in 2.2.11. So I'll upgrade and try again. -- Ed Avis <eda@xxxxxxxxxxxxx> --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
