[php-maint] Bug#535770: Segmentation fault with php 5.3

[jidanni at jidanni.org]

Package: php5
Version: 5.3.0-2
X-Debbugs-cc: mediawiki-l at lists.wikimedia.org

Hello. With an SVN version of Mediawiki,
Offline on my test wiki, calling
index.php?title=%E7%89%B9%E6%AE%8A:%E5%8F%83%E6%95%B8%E8%A8%AD%E7%BD%AE
(which is Special:Preferences), as a logged in user, causes
child pid 10600 exit signal Segmentation fault (11) as seen in
/var/log/apache2/error.log
The last lines in $wgDebugLogFile were:
AND page_title = '用戶' LIMIT 1 SQL: SELECT /* LinkCache::addLinkObj
Jidanni */ page_id,page_len,page_is_redirect FROM `page` WHERE
page_namespace = '4' AND page_title = '自動確認使用者' LIMIT 1
Unstubbing $wgAuth on call of $wgAuth::allowPropChange from
Preferences::profilePreferences

# dpkg -i *5.2.10*
dpkg: warning: downgrading libapache2-mod-php5 from 5.3.0-2 to 5.2.10.dfsg.1-1...
fixed it.

So, just like https://bugzilla.wikimedia.org/show_bug.cgi?id=9365 , this
is probably not a Mediawiki problem, but a php5.3 problem.
