dl() usage for cli php5

I'm getting segfaults at shutdown when using dl() with my extension - works perfectly if it's in php.ini (or if I run when compiled with --enable-debug a) is this a known issue? b) is it fixable for cli usage? I'm guessing this is because modules are destroyed before the objects that they created are . looking at main/main.c :php_request_shutdown_for_hook() - a temporary fix may be to check for sapi == cli and skip the zend_deactivate_modules, and add it to the sapi_deactivate_cli..
