Thanks for the quick answer.  A "cvs log" on vtkExtractVOI.cxx shows the
last change:

revision 1.24
date: 2001/01/22 12:48:07;  author: lawcc;  state: Exp;  lines: +7 -7
Inputs take images instead of structured points.  Also fixed memory leak.

That was 22 January.  Was the fix for vtkExtractVOI maybe not checked in?
Perhaps the fix was on a parent class?

I'm rebuilding as we speak just to make sure, but my last build was about a
week ago.

Thanks again,
