--- Comment #7 from Florian Weimer <fweimer at redhat dot com> 2013-01-31 11:05:48 UTC --- (In reply to comment #6) > Just write > number_of_elements_in_path+100U > or use unsigned type for > number_of_elements_in_path Thanks, this is helpful. It seems you need both (number_of_elements_in_path already is of type quint16), otherwise the expression is promoted to int. I think it might be a permanent fix (not dependent on current optimizer behavior) because of the GCC extension ensuring that unsigned -> int conversion is always defined. Interesting.
