[vtk-developers] TestImageDataLIC2D test failures

[Ken Martin]

OK using

https://open.cdash.org/index.php?project=VTK&filtercount=4&showfilters=1&filtercombine=and&field1=site/string&compare1=63&value1=hythloth&field2=buildstarttime/date&compare2=83&value2=2015-12-01&field3=buildname/string&compare3=64&value3=OpenGL1&field4=buildname/string&compare4=64&value4=External

the test passed on

https://open.cdash.org/viewUpdate.php?buildid=4148832  (Dec 13th 2015) as
well as lots of times before then. It has consistently failed since then.
The changes listed for the failing build are here:

https://open.cdash.org/viewUpdate.php?buildid=4148832 with authors of:

KWSys Upstream
David Gobbi
Ben Boekle
Utkarsh
Bill Lorensen
Brad King

none of the changes particularly look like an issue to me but I have not
looked closely.

I suppose we could try doing a git bisect of that day to see if a
particular change introduced the failure (or exposed a pre existing issue)
or if there was a system change that introduced the issue.
