Bug #71192 [Opn]: Segfault on Shutdown

Edit report at https://bugs.php.net/bug.php?id=71192&edit=1 ID: 71192 User updated by: michael at currinda dot com Reported by: michael at currinda dot com Summary: Segfault on Shutdown Status: Open Type: Bug Package: Reproducible crash Operating System: Ubuntu Precise PHP Version: 7.0.1 Block user comment: N Private report: N New Comment: Unfortunately I wouldn't be able to test it without YAML, this is on a live server. There doesn't seem to be a huge amount of rhyme or reason to the actual scripts that are crashing it. I've had a case where the same script, with slightly different database inputs ie. a different record is crashing it. I've also downloaded the database to my local machine, run the script on local (mac running same version, though not compiled) and it hasn't crashed.

What version of YAML do you have installed. Is there a specific script that is causing this, if so are you able to post it? thanks ------------------------------------------------------------------------ [2015-12-22 04:58:00] michael at currinda dot com Description: ------------ Segfault on shutdown, not sure what script is causing this but getting reports of unclean exits from browsers.
