[Insight-users] UpdateLargestPossibleRegion exception on largeimage

[Luis Ibanez]

Hi Normand,

Thanks for posting the details.

It seems that we can discard memory exhaustion as
the source of the problem.

We should suspect of a pointer misuse at this point.

Please post a minimal version of your code that is
compilable and still exhibits this behavior.


   Thanks a lot,


      Luis
