New Comment:
Please try to run `top`, `ps aux` and `host example.com`.
Do they work fine or segfault too?
I'm asking because of this:

This just in:
The script does not terminate. It ends like it's supposed to.
The segfault is put out when the scripts terminates. I don't know if
it's a child process that dies, or that the segfault resides in a
buffer untill termination or something.

I seem to have judged to fast before. But still: I can't surpress this
error. It's ugly!

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.
Actual result:
--
Segmentation fault on any line that resolves a hostname.
