[vtk-developers] Infovis-TestContingencyStatistics test failing since May 16; help

[Wylie, Brian]

Philippe Pebay is the developer of these classes/tests and he's in France right now, so might be hard to get his feedback on this. Apologizes for that...


I see Party Dave (partyd at kitware.com) committed something yesterday afternoon.. Does this perhaps fix it?

Subject: [vtk-developers] Infovis-TestContingencyStatistics test failing since May 16; help

Hi all,

For the first time ever, my dashboards are almost green (ok, I had to exclude some tests, but...)  The only failing test now is:

  Infovis-TestContingencyStatistics 

<http://www.cdash.org/CDash/testDetails.php?test=23410248&build=337229> 

It seems to be crashing only on this machine, and only since May 16. 
The backtrace is below.

Anyone have any ideas?  If someone knows this code, I can help debug it.  It repros.

Thanks,

Sean
