[Insight-developers] changes in level set routines since ITK 3.4 breaks itk-snap

[Luis Ibanez]

Hi Casey,

Could you please give us a hand by providing a description
of the circumstances in which this error becomes visible ?

E.g. a step-by-step set of instructions will be ideal.

We should then be able to introduce in ITK a new Nightly
test that exercise this same case, and then we can proceed
to fix the problem.


   Thanks for any advice,


       Luis
