Bug#666200: [php-maint] Bug#666200: php5-cgi: tt-rss backend.php crashes after update to php 5.4
Please install php5-dbg, dump a core and attach usable backtrace.

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. -- System Information: Debian Release: wheezy/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable'), (1, 'experimental') Architecture: i386 (i686) Kernel: Linux 2.6.38-2-686 (SMP w/2 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages php5-cgi depends on: ii libbz2-1.0 1.0.6-1 ii libc6 2.13-27 ii libcomerr2 1.42.1-2 ii libdb5.1 5.1.29-1 ii libgssapi-krb5-2 1.10+dfsg~beta1-2 ii libk5crypto3 1.10+dfsg~beta1-2 ii libkrb5-3 1.10+dfsg~beta1-2 ii libmagic1 5.11-1 ii libonig2 5.9.1-1 ii libpcre3 8.12-4 ii libqdbm14 1.8.78-2 ii libssl1.0.0 1.0.0h-1 ii libxml2 2.7.8.dfsg-7 ii mime-support 3.52-1 ii php5-common 5.4.0-3 ii tzdata 2012b-1 ii ucf 3.0025+nmu2 ii zlib1g 1:1.2.6.dfsg-2 php5-cgi recommends no packages.

Thomas, we don't need a full coredump, just a backtrace :). Install php5-dbg, and run the coredump through gdb. O.

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' --exec=/usr/lib/cgi-bin/php5 Should do it... O.

Hmm... looks like you need to add:
--symbols=/usr/lib/debug/usr/lib/cgi-bin/php5 to the command line.

forwarded 666200 https://bugs.php.net/bug.php?id=61557 thank you Hi Thomas, I have forwarded your bug to the upstream bug database. We don't patch (at least I don't remember it) XML functions so it looks like an upstream bug. Thanks for the information.
