Bug #51753 [Bgs]: Installing PECL extensions Memcached causes segfault.
Edit report at http://bugs.php.net/bug.php?id=51753&edit=1
ID: 51753
Updated by: rrichards@php.net
Reported by: sa at nkvdteam dot ru
Summary: Installing PECL extensions Memcached causes segfault.
Status: Bogus
Type: Bug
Package: Unknown/Other Function
Operating System: FreeBSD 7.2-RELEASE
PHP Version: Irrelevant
New Comment:
I would first look at the threading in libmemcache. To get a better idea
on what
is causing the crash, you need to use a debug build of libxml2.

But in any case it is not a php bug > bogus.

I wonder if it is really a libxml issue, but if it is the case, to
report the issue to the libxml developer would be the right way (or
freebsd if it is freebsd specific).

No.
Solution found and patch proposed. Do I need send it to FreeBSD team, or
only in this bug?

Does it crash without memcached?

Description:
------------
After installing and enabling memcached.so extension (pecl install
mecached), php segfaults on any action (e.g. php -m or php -v):
[root@node ~]# php -v
PHP 5.3.2 (cli) (built: May 5 2010 20:03:50) (DEBUG)
Copyright (c) 1997-2010 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies
Segmentation fault: 11 (core dumped)
Disabling all other modules (excl. memcached and session), recompiling
php and libxml2, reinstalling memcached.so does not fixes it.
Actual result:
