ID: 41290 Updated by: [EMAIL PROTECTED] Reported By: wyatt dot neal at ngc dot com -Status: Open +Status: Bogus Bug Type: Reproducible crash Operating System: RHEL4U4 PHP Version: 5.2.2 New Comment:
The backtrace clearly shows it's not PHP problem. Previous Comments: ------------------------------------------------------------------------ [2007-05-04 18:46:14] wyatt dot neal at ngc dot com Description: ------------ Running PHP version 5.2.2, I can consistently crash php (cli) with a *** glibc detected *** corrupted double-linked list Verified permissions to all files and paths. Running Openldap 2.3. The test code below should reproduce the error without fail. I've verified the same operations against Openldap with a client written in C and this error does not occur. I'll apologize ahead of time for any mis-spellings since I've had to retype the entire backtrace by hand. Reproduce code: --------------- <?php $host = "ldap://host.domain.com";; $tls_cacert = "/etc/openldap/cacerts/cacert.pem"; $tls_cert = "/etc/openldap/certificates/ldap-client.pem"; $tls_key = "/etc/openldap/certificates/ldap-client-key.pem"; putenv("LDAPTLS_CACERT=$tls_cacert"); putenv("LDAPTLS_CERT=$tls_cert"); putenv("LDAPTLS_KEY=$tls_key"); $result = ldap_set_option(NULL, LDAP_OPT_PROTOCOL_VERSION, 3); if(!$result) { exit(0); } $conn = ldap_connect($host); if(!conn) { exit(0); } $result = ldap_start_tls($conn); if(!result) { exit(0); } ?> Expected result: ---------------- A clean exit. Actual result: -------------- (gdb) run test.php ..... [New Tread -1208449344 (LWP 10103)] *** glibc detected *** corrupted double-linked list: 0x09e63d0 *** Program received signal SIGABRT, Aborted.
