Hi,
I am having a problem in my PHP extension and I am wondering if you can give me
some advise or even a pointer.
We have the following class object XQueryProcessor and XdmNode.
The following method takes the XdmNode as parameter:
XQueryProcessor.setContextItem(XdmNode)
Any idea what is going wrong in the code below? The XdmNode in my PHP class is
a wrapper for a C/C++ object which is held in the XQueryProcessor. Do I have to
add some special refcount to the PHP XdmNode?
This is giving a memory leak warning:

The code in question is at follows:
PHP_METHOD(XQueryProcessor, setContextItem)
{
char * context;
int len1;
zval* oth;
XQueryProcessor *xqueryProcessor;
if (zend_parse_parameters(ZEND_NUM_ARGS(), "z", &oth) == FAILURE) {
RETURN_NULL();
}
if(oth != NULL) {
zend_object* pobj = Z_OBJ_P(getThis());
xqueryProcessor_object *obj = (xqueryProcessor_object *)((char *)pobj -
XtOffsetOf(xqueryProcessor_object, std));
xqueryProcessor = obj->xqueryProcessor;
const char * objName =ZSTR_VAL(Z_OBJCE_P(oth)->name);
Z_ADDREF_P(oth);
if(strcmp(objName, "Saxon\\XdmNode")==0) {
zend_object *vvobj = Z_OBJ_P(oth);
xdmNode_object* ooth = (xdmNode_object *)((char *)vvobj -
XtOffsetOf(xdmNode_object, std));
if(ooth != NULL) {
XdmNode * value = ooth->xdmNode;
if(value != NULL) {
Z_ADDREF(*oth);
xqueryProcessor->setContextItem((XdmItem *)value);
return;
}
}
} else
