Bug #68514 [NEW]: Segmentation fault

From: sprotte at visionconnect dot de Operating system: openSUSE 12.3 PHP version: 5.6.3 Package: *General Issues Bug Type: Bug Bug description:Segmentation fault Description: ------------ Since updating to PHP 5.6 we got random segmentation faults in our PHP-FPM environment. I have not been able to reproduce this. The amount of segmentation faults raised to a very noticable level and I configured PHP to save core dumps to be able to investigate further. After just this configuration change, the amount of segmentation faults has massively reduced, but I have gotten the same error 3 times in 3 days (see 1st backtrace) and another error today (see 2nd backtrace).
