From backtrace, doesn't seems a PHP bug, reaffecting.
Please try to disable Xdebug to confirm bug is in this extension.
http://bugs.xdebug.org/view.php?id=1043
Please also provide step to "simply" reproduce. Also with as much as possible extension disabled (there is really a lot enabled, according to attached list).
Sorry I cannot provide more information because I don't have an access to this system anymore.
Upstream bug closed, and not enough information.
