Hello Even,

thank you for the reply. I attached a minimal test that compares as you
suggested to buffers.
When I use CPLSetConfigOption("ECW_CLEVER", "NO"); two buffers are equal.
CPLSetConfigOption("ECW_CLEVER", "YES"); two buffers are different. A 4
bands image can be donwloaded from this link :

I do not know if it is an issue in GDAL, however there is something strange
with the usage of sCachedMultiBandIO from ECWDataset.


PS : sorry for duplicate
