Bug #79902 [Opn->Fbk]: *** Error in `/usr/bin/php': free(): invalid pointer

Edit report at https://bugs.php.net/bug.php?id=79902&edit=1 ID: 79902 Updated by: cmb@php.net Reported by: pranabesh_paul at yahoo dot co dot in Summary: *** Error in `/usr/bin/php': free(): invalid pointer -Status: Open +Status: Feedback Type: Bug Package: SNMP related Operating System: CentOS 7 PHP Version: 7.3 -Assigned To: +Assigned To: cmb Block user comment: N Private report: N New Comment: 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?
