Previous Comments: ------------------------------------------------------------------------ [2008-06-09 16:14:00] dmda at yandex dot ru Description: ------------ if -z and -m command line options are used together, php-cgi will crash. It happens b'ze print_extensions() function in cgi_main.c has a serious flaw: 1) it first makes a copy of the main list of zend_extensions 2) then it dumps out the content 3) then it destroys its copy of the list Duding phase 3, the list destructor is called and it UNLOADS all the zend_extensions. SHULD be noted that at this time the main list still has original copies of zend_extensions and that's why php will crash during shutdown in attempt to walk through the list and shutdown the extensions. You may replicate the problem with _ANY_ zend_extension. Better to do it under Windows that unmaps memory regions and shutdown will try call non-existing code. So the crash is inavoidable.
