Bug #68439 [NEW]: Various crashes, mostly accel_startup and internet strings

From: mattficken Operating system: Windows PHP version: Irrelevant Package: opcache Bug Type: Bug Bug description:Various crashes, mostly accel_startup and internet strings Description: ------------ Many crashes in Opcache (on Windows) have been reported to Microsoft's Watson service by the Windows Error Reporting feature on Windows. I am filing a bug report containing all those crashes so that we have it recorded and public. Many reports use a different version of Opcache and PHP together due to some user misconfiguration (fe, opcache version 5.5.10 and php 5.5.15). Some crash reports do not include stack traces or have symbol misalignment. Many crashes are only reported for x64 builds, which are experimental. None of those reported crashes are included here. All these crashes are valid stack traces, real crashes with matching opcache x86 and x86 php builds. Most of the crashes are in php_opcache!accel_startup and php_opcache!accel_new_interned_string in 5.5 and 5.6 (where we see most other crashes in opcache), all from Fast-CGI Actual result: -------------- Crash #1 (Watson #-557903867) exit code: INVALID_POINTER_READ 0xc0000005 in php_opcache.dll PHP: 5.5.1 FastCGI (php-cgi) 00aef524 6e54ce4f php_opcache!accel_startup+0xa605 [c:\php-sdk\php55\vc11\x86\php-5.5.1\ext\opcache\zendaccelerator.c @ 2536] 00aef530 6e68b85d php5!zend_extension_startup+0xf [c:\php-sdk\php55\vc11\x86\php-5.5.1\zend\zend_extensions.c @ 154] 00c57008 0133067c php5!zend_llist_apply_with_del+0x2ad3fd [c:\php-sdk\php55\vc11\x86\php-5.5.1\zend\zend_llist.c @ 178] WARNING: Frame IP not in any known module.
