Public bug reported:
Upstream php5 bug: https://bugs.php.net/bug.php?id=64535
Bug description:
- I installed vanilla WordPress 4.1 (from wordpress.org, not the Ubuntu repos)
- Several of the configuration pages, in particular
wp-admin/options-general.php, would give NO RESPONSE errors when I browsed to
them.
- The apache error log showed that apache2 was SEGFAULTing
- The log also showed that a coredump was being dropped in /etc/apache2
- I started gdb with /usr/sbin/apache2 and loaded the core file. The
backtrace is below; the core file is also attached.
- The backtrace showed that the last non-library frame was
php_ssh2_fopen_wraper_parse_path () in /usr/lib/php5/20121212/ssh2.so.
- A quick Google search turned up the PHP5 bug above
- I rebuilt php-ssh2 with the patch from the upstream bug (reproduced below)
and it solves the problem.
Relevant package versions:
- Up-to-date 14.04 install (as of 3 January 2015)
- libssh-php 0.12-1
- php5 5.5.9+dfsg-1ubuntu4
- apache2 2.4.7-1ubuntu4
- openssh 1:6.6p1-2ubuntu1
** Affects: php-ssh2 (Ubuntu)
