Edit report at https://bugs.php.net/bug.php?id=78754&edit=1 ID: 78754 Updated by: cmb@php.net Reported by: deivid dot garcia dot garcia at gmail dot com Summary: Opcache PHP Crash Status: Open Type: Bug Package: opcache Operating System: Windows Server 2016 Standard PHP Version: 7.2.24 Block user comment: N Private report: N New Comment: Some questions: * Which build are you using exactly? * Do you use opcache.file_cache_fallback, or opcache.file_cache_only? * Do you have opcache.file_cache_consistency_checks enabled? * What's your opcache.log_verbosity_level value? * Are there any relevant messages in opcache.error_log? * Could you provide a backtrace[1] (there might be one contained in the WER report, but I'm reluctant to download 20GB) * Could you try with PHP 7.2.24 or even 7.3.11?

Faulting application name: php-cgi.exe, version: 7.2.22.0, time stamp: 0x5d664a16 Faulting module name: ntdll.dll, version: 10.0.14393.447, time stamp: 0x5819bc32 Exception code: 0xc0000409 Fault offset: 0x000000000009520f Faulting process id: 0xa18 Faulting application start time: 0x01d58ccb45755151 Faulting application path: d:\chef\_apps\chf_magento2_jvgo\runtime\php\php-cgi.exe Faulting module path: C:\Windows\SYSTEM32\ntdll.dll Report Id: e561a003-7e6b-4ae9-882c-1066267c168a Faulting package full name: Faulting package-relative application ID: The error goes away if: [A] Disable opcache extension with: opcache.enable=0 [B] Delete the contents of the opcache.file_cache (works for a while, and the error shows up again when PHP tries to read from the file cache). This totally points to some sort of condition in the cached files: * They might be corrupted in some way? * The issue might be related to LongPaths on Windows? ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78754&edit=1
