Summary of discussions with David. I am not able to reproduce the 'Test Fail' issue. However, log indicates an issue in the test code. David has validated the patch and I will send it out soon.
The test case taking long time to complete happens when the code is compiled with '-O0 -g', but the test case itself completes. The test cases are currently tuned to take less time when compiled with '-O3'.
