<div dir="ltr"><div><div>Hello again all,<br></div><div><br>The Windows CDash@Home client is online again and has now fully caught up with its backlog of queued experimental builds.<br><br>The 8 tests that were failing today [1] on that machine should also be fixed now. The problem was due to 2 corrupt Baseline files which didn't match their correct MD5, likely caused by an unfortunately timed reboot. The issue has been corrected for future builds.<br>
<br></div>Changes to the logging configuration on that machine have also revealed a bug in itkSampleToHistogramFilterTest2 and itkSampleToHistogramFilterTest6, where these tests were not properly failing. Indeed, these tests should have been failing more regularly, as the tested class, SampleToHistogramFilter, has a troublesome bug whereby some optimized builds of MSVC are producing incorrect behavior inside a loop [2]. I've reproduced the failure, albeit with some difficulty, as attaching any sort of debugging to the inner loop changes its behavior and prevents the failure [3]. I'm still actively working on the issue. In the meantime, I've reduced the level of build logging so that the 2 tests in question no longer timeout.<br>
<br></div>I'll continue to monitor future builds closely, if any new issues pop up.<br><div><div><br>[1] <a href="http://open.cdash.org/viewTest.php?buildid=3224829">http://open.cdash.org/viewTest.php?buildid=3224829</a><br>
