[Insight-users] WG: Abnormal termination error with erotion filter!!!

[salah]

I am almost sure, it is a bug in the erosion filter.

It works fine many times as long as you feed it
with images of the same dimensions. It will terminate
the program abnormally if you re-run it with an image
of new dimensions.

Could anybody please verify this...
