<div>> I check the return value is 0 which means pthread_getattr_np goes </div>

<div>> So, I think there may be something wrong with this function.</div>
<div> </div>
<div>Maybe the stack related parts are not returned by pthread_getattr_np(). </div>
<div>Please add a ticket for this. You may also implement the missing feature </div>
<div>and add a test case to testsuites/psxtests/psxgetattrnp01.</div>
