Can you reproduce this segfault with any of the actively supported PHP versions[1].

This bug is triggered in a production setup with many requests and it does not seem to be triggered by specific requests. This is triggered in php-fpm and does not seem to be connected to a specific request. We get the segfaults every few hours. I can imagine this bug gets triggered because RSHUTDOWN is not run, since this would set the DATEG(tzcache) = NULL; and thus not trigger the if condition in zm_activate_date: if (DATEG(timezone)) { efree(DATEG(timezone)); } Extensions loaded: mysqlnd.so opcache.so pdo.so xml.so apcu.so calendar.so ctype.so curl.so dom.so exif.so fileinfo.so ftp.so gd.so geoip.so gettext.so iconv.so igbinary.so intl.so json.so mbstring.so mysqli.so pdo_mysql.so phar.so posix.so readline.so redis.so shmop.so simplexml.so sockets.so sysvmsg.so sysvsem.so sysvshm.so tideways.so tokenizer.so wddx.so xmlreader.so xmlwriter.so xsl.so zip.so apc.so Expected result: ---------------- No segfault Actual result: -------------- GDB Backtrace: #0 zend_mm_free_heap (ptr=0x7fcab4135270, heap=0x7fcacd400040) at ./Zend/zend_alloc.c:1388 #1 _efree (ptr=0x7fcab4135270) at ./Zend/zend_alloc.c:2456 #2 0x000055b8b5a60795 in zm_activate_date (type=<optimized out>, module_number=<optimized out>) at ./ext/date/php_date.c:729 #3 0x000055b8b5c1b7b0 in zend_activate_modules () at ./Zend/zend_API.c:2600 #4 0x000055b8b5bae7e6 in php_request_startup () at ./main/main.c:1694 #5 0x000055b8b5a5f870 in main (argc=<optimized out>, argv=<optimized out>) at ./sapi/fpm/fpm/fpm_main.c:1927 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79190&edit=1
