Bug #68623 [NEW]: php - switch return - php-fpm SIGSEGV

From: claude dot ws01 at gmail dot com Operating system: CentOS 6.6 PHP version: Irrelevant Package: FPM related Bug Type: Bug Bug description:php - switch return - php-fpm SIGSEGV Description: ------------ php v5.5.19 centos 6.6 nginx v1.6.2 (tracking sys would not accept 5.5.19 as php version) Getting a SIGSEGV in php-fpm on the return statement within a switch-case block. I did not analyse the core dump. But pin-pointed the location in the php code. A while ago, after updating php, recompiling nginx, I got the same issue, same class, other function, same switch-return concept, that I solved by changing it with an if-then-else. Last week I did another php update, and then another function caused same SIGSEGV, same class, same switch-return concept, and solved it by putting the return after the switch. I'm using same php v5.5.19 in a windows stack and linux server, and this issue is only on the linux server. I do not know what more information I can provide. My objective is only to report it, as I have solved it, but worth reporting Kind regards Claude.
