That doesn't seem right at all.  Calling the "with plugin" variant
requires you
to pass something that has a signature like fprintf(). Did you call that
directly or via the wrapper rtems_stack_checker_report_usage()?

Can you run the fileio sample and try the stackuse command? That test should
just work.
