OVAL Interpreter

Running the latest vulnerabilities for Windows XP, I ran into this
recursion problem (stack overflow).

Goes on for a long time.

The object that seems to be the trigger is:
<registry_object id="oval:org.mitre.oval:obj:532" version="1"
xmlns="http://oval.mitre.org/XMLSchema/oval-definitions-5#windows">
<hive>HKEY_USERS</hive>
<key operation="pattern
match">^S-[-0-9]+\\Identities\\\{[-0-9A-Z]+\}\\Software\\Microsoft\\Outlook
\ Express\\5\.0\\Mail$</key>
<name operation="equals">ShowHybridView</name>
</registry_object>

I attached a xml file with just that test in it.
