sound like a problem with CImg.

David Tschumperlé, the CImg author has contacted me to port digiKam
code to new GMic framework which include now greystoration algorithm.
New CImg do not compile with digiKam due to lack greystoration code,
and will not be maintened in the future.

In GMic, a lots of code have been rewritten and sound like more
stable. I don't have yet found time to port code from digiKam
