[Insight-developers] itkMattesMutualInformationImageToImageMetricTest failures

[Luis Ibanez]

Hi Bill,

I just ran DeformableRegistration12Test1 with 1 thread,
and confirmed your observation that in this case the
test passes fine. ("redwall", Win64, VS8, Windows Vista).

This is very useful indeed...

The test is only failing when disabling the UseCache
option, and using multiple threads.  This reduces the
number of suspect lines to a relatively small set...


   Thanks !


      Luis
