Comment 12 Remi Collet 2014-03-26 13:26:46 UTC 
From backtrace, doesn't seems a PHP bug, reaffecting.
Comment 13 Remi Collet 2014-03-26 13:36:40 UTC 
Please try to disable Xdebug to confirm bug is in this extension.

Comment 15 Remi Collet 2014-03-26 13:50:53 UTC 
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.
Comment 17 Remi Collet 2014-06-25 09:19:08 UTC 
Upstream bug closed, and not enough information.
