****************************************************************************

* Symbol loading may be unreliable without a symbol search path.           *

* Use .symfix to have the debugger choose a symbol path.                   *

* After setting your symbol path, use .reload to refresh symbol locations. *

* Symbols can not be loaded because symbol path is not initialized. *

*   using the _NT_SYMBOL_PATH environment variable.                 *

*   using the -y <symbol_path> argument when starting the debugger. *
