Description:
------------
When executing xml_parse on a parser handle that was created using
xml_create_parser_ns, the script fails.
Reproduce code:
---------------
// dummy handlers
function defaultTagHandler($parser,$data){
echo $data;
}
//cont'd
function namespaceBla($parser,$user_data,$prefix){
}
// read a file
$filename = "demo.xml";
$file_data = implode("",file($filename));
$parser = xml_parser_create_ns();
xml_set_default_handler($parser,"defaultTagHandler");
xml_set_start_namespace_decl_handler($parser,"namespaceBla");
xml_set_end_namespace_decl_handler($parser,"namespaceBla");
// crashes here.
xml_parse($parser,$file_data);
Expected result:
----------------
to echo some node data.
Actual result:
--------------
bus error.
