Bug#666200: php5-cgi: tt-rss backend.php crashes after update to php 5.4

Package: php5-cgi
Version: 5.4.0-3
Severity: normal

Dear Maintainer,

this problem occurs with the non debian package tt-rss trunk:
https://github.com/gothfox/Tiny-Tiny-RSS.git
commit c20b5168b5a9103e1a2633973492c89fa03a5a57
against postgresql via php5-pgsql

After upgrading to php5 5.4.0 this application crashes php-cgi with
sporadic segfaults when calling the json backend.php of this system.
I tried to remove any tunings in php.ini.

I removed php5-xcache due to known issues (#665006) but the segfaults
still occur. Stuff done with standard distribution

 * apt-get install lighttpd php5-cgi postgres php5-pgsql
 * lighty-enable-mod fastcgi
 * lighty-enable-mod fastcgi-php
 * lighty-enable-mod pgsql

Then

 * Git clone above git to /var/lib/tt-rss
 * lighty config: alias.url += ( "/tt"  => "/var/lib/tt-rss" )
 * create a postgres database and fill it with tt-rss' sql scheme
 * configure tt-rss (set database parameter in config.php)
 * restart lighttpd
 * open browser and use this application

Expected outcome:

 * Working with the application without problems

Actual outcome:

 * syslog reports: php-cgi segfault
 * lighttpd reports: connection failure to php-cgi
 * application reports: wrong header file

This application loads static files (js, css) and does continuous
calls to the application's backend.php. I append a coredump of
the segfault (maybe with the next post)

Other php applications (also selfmade, like owncloud, horde4) work
as expected - after uninstalling php5-xcache of course.

Please install php5-dbg, dump a core and attach usable backtrace.

One more thing. Could you please switch your locale to en_US or just C
before you run gdb?

LC_ALL=C gdb --core=corefile --eval-command='bt full'

Should do it...

O.

Hm, locales, there are locales... Sorry
