Tests fail under Windows 10 static debug build

After I build windows 10 static debug, all tests that open a render window segfault. Specifically, I get this error before a nullptr access:

Generic Warning: In C:\akit\vtk\src\Rendering\Core\vtkRenderWindow.cxx, line 35
Error: no override found for 'vtkRenderWindow'.

I'm using VS2017, with these changes from VTK defaults:

set(BUILD_SHARED_LIBS "OFF" CACHE BOOL "")
set(BUILD_TESTING "ON" CACHE BOOL "")
set(CMAKE_BUILD_TYPE "Debug" CACHE STRING "")
