Hi Thang,

That is a different test. The test that is having the problem is:

./testsuite/systemtap.samples/tcptest.stp

There is another buildok test that has a similar name.

Are you able to run the complete tests and get similar results to what was 
posted earlier in terms of number of successes and failures?
