Edit report at https://bugs.php.net/bug.php?id=60167&edit=1 ID: 60167 Updated by: thekid@php.net Reported by: thekid@php.net Summary: Crash / memory corruption Status: Open Type: Bug Package: COM related Operating System: Windows PHP Version: 5.4.0 -Assigned To: +Assigned To: dmitry Block user comment: N Private report: N New Comment: Dmitry, can you review this patch? I'm not sure this is the right place to fix this issue - it's related to the literal caching in the Zend Engine's method call init opcodes (ZEND_INIT_[STATIC_]METHOD_CALL) and might need to be addressed there instead of having to change PHP extensions. Thanks!
