[vtk-developers] BandedPolyDataContourFilter failes to compile on Ubuntu 14

Tue Feb 5 16:37:12 EST 2019

But my ubuntu compiler was 4.8.4. And it's c++11 support is spotty as
pointed out by this error. I don't believe there are any dashboards for
that old compiler. So it isn't really supported by VTK.
