Bug description: Segmentation Fault in Function node_list_wrapper_dtor
Description:
------------
We are getting not steadily reproducable segmentation fault in this
function. From one recursive Call to the other it appears the a
NULL-Pointer (in node) is somehow casted to 0xffff0000. We suspect that
this might be a casting problem between xmlNodePtr and xmlAttr
/* destroyref is a bool indicating if all registered objects for nodes
within the tree should be destroyed */
static inline void node_list_wrapper_dtor(xmlNodePtr node, int destroyref
TSRMLS_DC)
{
while (node != NULL) {
node_list_wrapper_dtor(node->children, destroyref TSRMLS_CC);
switch (node->type) {
/* Skip property freeing for the following types */
case XML_ATTRIBUTE_DECL:
case XML_DTD_NODE:
case XML_ENTITY_DECL:
case XML_ATTRIBUTE_NODE:
break;
default:
/* Attribute Nodes contain accessible children
Call this function with the propert list
attr_list_wrapper_dtor(node->properties); */
node_list_wrapper_dtor((xmlNodePtr) node->properties,
destroyref
TSRMLS_CC);
}
if (destroyref == 1) {
node_wrapper_free(node TSRMLS_CC);
} else {
node_wrapper_dtor(node);
}
node = node->next;
}
}
