The shell memory dump commands (`mdump`, `wdump`, `ldump`)have a bug when invoked without arguments.When these commands are called without providing a memory address argument (e.g., just typing `wdump`), the `args_parse()` function sets the address pointer to `NULL`. Subsequently, `rtems_mdump()` attempts to dereference this NULL pointer, leading to undefined behavior and potential system crash
