Bug in DOM document.c php_dom_ctx_error_level()

The php_dom_ctx_error_level() function in DOM document.c assumes that input->filename is always non-null. This is not true when the file is an entity. You can trigger this by killing your Internet connection and then loading any XML file that references an external entity. For example: <!ENTITY % HTMLlat1 PUBLIC "-//W3C//ENTITIES Latin 1 for XHTML//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml-lat1.ent"> %HTMLlat1; ]> A patch to fix this is available at: http://www.trachtenberg.com/patches/php_dom_ctx_error_level.txt -adam -- adam@trachtenberg.com
