But QOM\ngoes a bit further and purposefully sets the class pointer to NULL to\nhelp find use-after-free.  It worked :-)\n\nCc: Andreas Faerber \u003cafaerber@suse.de\u003e\nReported-by: Markus Armbruster \u003carmbru@redhat.com\u003e\nSigned-off-by: Anthony Liguori \u003caliguori@us.ibm.com\u003e\n",
