[vtk-developers] CMake Segfaults while configuring VTK

[Kevin H. Hobbs]

Stephen,

My VTK Dashboard builds use CMake from my CMake dashboard build.

The hosts are bubbles and murron.

On the Aug. 2 the VTK builds on both hosts began segfaulting at
the configure step.

You had a large commit to CMake that showed up on that dashboard
cycle.

I switched my cmake build type from Release to Debug and ran in gdb.

I get this at the end of :

gdb) run ../VTK
