i think it was due to the layout of some temporary /scratch buffer
maybe in the emulated_edge_mc() call in ff_snow_pred_block() but
iam not sure
as stride becomes too small its no longer possible to store some elements
that is when they are larger
The assert should possibly be made conditional on such too large
blocks occuring when stride is too small
