RE: Summary of nightly testing 20061016 (failed to retrieve return value location)

Hi Will,

Sorry for the confusion.  The test I used 

./testsuite/systemtap.samples/tcptest.exp (tcptest.stp)

Occasionally it fails due to TCP traffic, but not "$return" error.

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?
