[Timothee Evain]

Hi Brad,

I'm on 4.10(.0).
Thanks for the follow-up, I will take a look.

What version of ITK are you using?

If this transform originated from IO, then there is a patch in 4.10.1 that should address the problem so that the more robust and safe dynamic_cast can stilll be used.

HTH,
Brad
