#36206 [Opn->Bgs]: LDAP in nsswitch.conf causes segfault when resolving hostnames in PHP

ID: 36206 Updated by: tony2001@php.net Reported By: arnout at argeweb dot nl -Status: Open +Status: Bogus Bug Type: CGI related Operating System: freeBSD 5.4 PHP Version: 5.1.2 New Comment: Here: http://unix.derkeiler.com/Mailing-Lists/FreeBSD/stable/2005-11/0315.html you can find that this problem also happens with Python on FreeBSD (with the very same backtrace). So it's not PHP problem, but some FreeBSD issue.

Do they work fine or segfault too? I'm asking because of this: http://lists.freebsd.org/pipermail/freebsd-bugs/2004-April/006201.html ------------------------------------------------------------------------ [2006-01-30 12:25:00] arnout at argeweb dot nl 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. root@host: / # echo "<? echo gethostbyname( 'php.net' ); ?>" | php 64.246.30.37Segmentation fault (core dumped) I seem to have judged to fast before. But still: I can't surpress this error. It's ugly! ------------------------------------------------------------------------ [2006-01-30 12:01:41] arnout at argeweb dot nl status change ------------------------------------------------------------------------ [2006-01-30 12:00:33] oersoep at gmail dot com #0 0x00000000 in ??
