php_opcache crash - memory access violation

Description

I don't know how to recreate the problem. it occurs on our production server, sporadically. 6x in past 4 days. never happened on old server (Windows 2012 R2) running same versions of PHP (8.0.14 x64 thread-safe) and apache httpd (2.4.51 x64), and the same opcache configuration. We are not using JIT.

Windows Event Log shows:

Running Windows DebugDiag tool, with PHP 8.0.14 symbols loaded, gives the report attached here:
opcache-crash-analysis.pdf

PHP Version

PHP 8.0.14

Operating System

Windows Server 2019; apache httpd 2.4.51 x64

Iniziare con il file opcache-crash-analysis.pdf allegato, la configurazione di php.ini e i dettagli dell'errore in Windows Event Log per PHP 8.0.14. L'issue sarà pronta solo quando sarà possibile riprodurre la violazione di accesso sporadica o ricondurla a una causa concreta e sarà dimostrato un fix verificato.
