   	391. identity_transfer: Passing times as argument 2 to constructor for class HttpClient, which sets client.m_times to that argument. [show details]
   	392. tainted_data_transitive: Call to function HttpClient with tainted argument times transitively taints client.m_times. [show details]
266                HttpClient client(threads, times, ofile);
   	393. Condition delay > 0, taking true branch.
267                if(delay > 0)
268                    client.setDelay(delay);
   	394. upper_bounds: Checking upper bounds of signed scalar client.m_times by taking the true branch of client.m_times < 1.
   	395. upper_bounds: Checking upper bounds of signed scalar client.m_times by taking the true branch of client.m_threads > client.m_times.
   	
CID 1514430 (#1-6 of 6): Untrusted value as argument (TAINTED_SCALAR)
        396. tainted_data: Passing tainted expression client.m_times to sendSoapRequest, which uses it as an allocation size. [show details]
   	Ensure that tainted values are properly sanitized, by checking that their values are within a permissible range.
269                client.sendSoapRequest(url.str(), soapaction, in_fname.str());
