I do nightly builds of the VTK project with recent clang (that I manually
update occasionally).  VTK with UBSan build with clang r315034.  Then I updated
to r316042 and it failed to build.  I updated just now to r316166 and it still
fails, with the message below.

I've attached the .c and .sh files.  The .crash file the message mentions isn't
actually there for some reason.
