WSDL2C generates improper code

Stub generated by WSDL2C contains bug, in generated code we can see something like:

soap_act = axis2_options_get_soap_action( options, env );

if (NULL == soap_act)

{ is_soap_act_set = AXIS2_FALSE; soap_action = "http://dummy/SampleService/dummyRequest"; soap_act = axutil_string_create(env, "http://dummy/SampleService/dummyRequest"); axis2_options_set_soap_action(options, env, soap_act); }

axis2_options_set_soap_version(options, env, AXIOM_SOAP11);

ret_node = axis2_svc_client_send_receive_with_op_qname( svc_client, env, op_qname, payload);

if (!is_soap_act_set)

{ axis2_options_set_soap_action(options, env, NULL); axis2_options_set_action( options, env, NULL); }

if(soap_act)

{ axutil_string_free(soap_act, env); }

The problem is that soap_act string should be freed only in case if it wasn't retrieved from options, and was created with axutil_string_create() call
If soap_action parameter will be set in options, existing implementation will retrieve that string with axis2_options_get_soap_action() call, and then free it, each next subsequent call will cause crash (because it will try to release already freed memory)
