XMLQuery bug?

The following query:

SELECT
XMLQuery('<category>{
for $d in /categories//*[@id="CA00PE004D"]/* let $k := ora:view("objects")/object[category/@id = $d/descendant-or-self::category/@id]
return <category count="{count($k)}" id="{$d/@id}" text="{$d/@title}"/>
}</category>' passing object_value returning content).getCLOBVal()
"cats"

FROM categories;

cause "ORA-19112: java.lang.OutOfMemoryError". But

SELECT
XMLQuery('<category>{
for $d in /categories//*[@id="CA00PE004D"]/* let $k := ora:view("objects")
return <category count="{count($k)}" id="{$d/@id}" text="{$d/@title}"/>
}</category>' passing object_value returning content).getCLOBVal()
"cats"

FROM categories;

works well.

What's wrong??
