Did shortly look at the source code, but I couldn't figure out, why it sefgaults. Something bad happens in if ((intern = (dom_object *) php_dom_object_get_data((void *) obj))) { in the function zval *php_dom_create_object(xmlNodePtr obj, int *found, zval *wrapper_in, zval *return_value, dom_object *domobj TSRMLS_DC) Maybe Rob looks into it later, or when I have more time ;) ------------------------------------------------------------------------ [2004-07-17 12:09:28] chregu@php.net I can reproduce it (latest CVS HEAD)..
