I cannot see the bug in virParseXMLDevice. The 'error' label sequence is ended by 'goto cleanup', and 'cleanup' sequence calls xmlFreeDoc(xml). Is it not the way to free the xmlDocPtr object 'xml'? Maybe I should reverse the sequence order to be more clear, as follows: + goto cleanup; +error: + free(buf.content); + buf.content = NULL; +cleanup: + if (xml != NULL) + xmlFreeDoc(xml); + return buf.content; "Daniel P.

If you take 'goto errror' path through the function, then the xmlDocPtr object will never be free'd. Thanks for taking the time to implement all this !
