dukky.c:dukky_push_handler_code_()
does
exc = dom_element_get_attribute(ele, onname, &val);
to get the attribute, if its missing the dom call succeeds with val == NULL
I think the error trap below needs to cope with that
|
|
|
|
|
|
prevented null deref due to missing attribute on dom node |
|
|
|
|
|
Confirmed fixed in 3.4 release |
