    SafeRTOS xTaskCreate failure

    I'm attempting to build up my first SafeRTOS application.  As I understand the processes, After initiaIizing the scheduler, I must have at least one task created before I can start the scheduler.  I have two task initialization routines, both of them are basic, and each checks the call to xTaskCreate for a sucessful return, like this one:

    int MasterTask::init(void)
    {
      if(xTaskCreate(&(this->runTask),
                     (signed portCHAR *)"MasterTask",
                     (signed portCHAR *)_taskStack,
                     sizeof(_taskStack),
                     NULL,  //pointer set when task created
                     PRIORITY_MASTER_TASK,
                     NULL) //reference to created task
         != pdPASS)
      {
        printf("MasterTask Init Flunked.\n");
        return 1;
      }
      printf("MasterTask Initialized.\n");
      return 0;
    }

    Yes, I am attempting to use a c++ static member function as the task function.  The problem I am running into is that I have another class encapsulating another task, and whichever init function I call second will return with failure.  Additionally, the call to xTaskStartScheduler returns, even if I initialize only one of the tasks. 

    Can someone tell me what I might be doing wrong, and where I could learn about troubleshooting strategies when calls to SafeRTOS API functions fail?  Is there a non-ROM version that I can utilize in debug mode?

      Update: I have created task functions outside the class for the tasks, there is no change in behavior.
