Description: ------------ Any hostname resolve in PHP causes a segmentation fault. It only happens when this file contains the ldap keyword. When removed, everything works fine. Everything works great when using modphp. It only happens when using the executable. [EMAIL PROTECTED]: / # cat /etc/nsswitch.conf group: files ldap group_compat: nis hosts: files dns networks: files passwd: files passwd_compat: nis shells: files We've seen it on two seperate systems. It's on PHP versions 5.0.5, 5.1.1 and 5.1.2 Server #1: openldap 2.2.30 nss_ldap 1.244 php 5.0.5 FreeBSD 5.4-RELEASE-p8 Server #2: nss_ldap-1.239 openldap-client-2.2.27 php 5.1.2 FreeBSD 5.4-RELEASE-p8 Reproduce code: --------------- [EMAIL PROTECTED]: / # echo "<? echo gethostbyname('php.net'); ?>" | php [EMAIL PROTECTED]: / # echo "<? mysql_connect( 'badgerbadger', '', '' ); ?>" | php #!/usr/local/bin/php <?php // this echo gethostbyname( 'php.net' ); // AND this too mysql_connect( 'blahdieblah', '', '' ); // and anything that resolves. ?> Expected result: ---------------- An IP-address and an error because the mysql host doesn't exist.
