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. Test script: --------------- static function get-a-SIGSEGV-without-any-result-returned() { switch (PHP_OS) { case 'WINNT': $result = utf8_encode(strftime($Language->getDateFormatLong(), mktime($hour, $minute, $second, $month, $day, $year))); return $result; default: $result = strftime($Language->getDateFormatLong(), mktime($hour, $minute, $second, $month, $day, $year)); return $result; } } static function get-the-result-returned-without-SIGSEGV() { switch (PHP_OS) { case 'WINNT': $result = utf8_encode(strftime($Language->getDateFormatLong(), mktime($hour, $minute, $second, $month, $day, $year))); break; default: $result = strftime($Language->getDateFormatLong(), mktime($hour, $minute, $second, $month, $day, $year)); } return $result; } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=68623&edit=1
