There was indeed a bug with clumps (fixed), but the thing I don't understand is the branch did not contain the changes. Bazaar branches are not quite user-friendly for commits/updates... Klaus, you probably didn't try the good code (but then how did you spot the bug? I'm lost...). Could you send me a copy of the core/bound.hpp you downloaded, just to be sure?
