I can not reply to rtems-devel mail list, so I have to send again.
Sorry for the rush reply eariler.
I do know this is a bug or I just use it in a wrong way. I need to make sure
that no one has encountered this problem like me before, then I will report a
bug.
Best wishes,

Maybe the stack related parts are not returned by pthread_getattr_np().
Please add a ticket for this. You may also implement the missing feature
and add a test case to testsuites/psxtests/psxgetattrnp01.
