Operating system: Debian (sid), 2.6.26 kernel
PHP version:      5.2.7RC3
PHP Bug Type:     Reproducible crash
Bug description:  Mediawiki hangs since 5.2.7rc2 and later

Description:
------------
Compiling all php versions with the same options and disabling all
extensions results in only 5.2.7rc1 running mediawiki stable (for a few
weeks now, basically as from time it was released) via fastcgi/php-cgi.

With 5.2.7rc2 and rc3 the php-cgi childs start to hang with 100% cpu-load
on nearly all requests, some work tho until all proc are at 100%.

Reverting to rc1 everything works like a charm.

Logs show nothing except timeout after xxx seconds.

Reproduce code:
---------------
my compile-options:

'./configure' '--with-mysql=/usr/local/mysql' '--with-openssl' '--with-gd'
'--enable-ftp' '--with-bz2' '--enable-sysvsem' '--enable-sysvshm'
'--enable-sockets' '--with-gettext' '--with-jpeg-dir=/usr/lib'
'--enable-exif' '--with-png-dir=/usr/lib' '--enable-zend-multibyte'
'--with-zlib-dir=/usr/include' '--enable-fastcgi' '--disable-cli'
'--enable-discard-path' '--enable-mbstring' '--without-sqlite'
'--enable-inline-optimization' '--disable-debug' '--enable-bcmath'
'--with-mcrypt'

Expected result:
----------------
work :-)

Actual result:
--------------
doesn´t work :-)
