Previous Comments: ------------------------------------------------------------------------ [2021-09-29 15:58:11] cmb@php.net Does this still happen with any of the actively supported PHP versions[1]? If so we need a reproduce script and/or a stack backtrace with debug symbols[2], although on a quick glance this might be caused by an earlier memory corruption. Is OPcache enabled? Does it also happen with OPcache disabled?
