#23162 [Opn]: user_error() crashs if $error_msg > 1024 bytes

ID: 23162 Updated by: jay@php.net Reported By: dimon at postmark dot net Status: Open Bug Type: Reproducible crash Operating System: Windows 2000 Server PHP Version: 4.3.1 New Comment: I have no idea if this hurts anything (hasn't given me any trouble), but adding "z_context->is_ref = 1;" to zend.c before calling call_user_function_ex() in zend_error() seems to fix the "$context passed by reference" segfault. Not being much of a ZE engine hacker, I don't know if that makes things better or worse.
