It's not possible to mathematically guarantee it to work 100% of the time. The best you can do if you come across this is to change something, such as degree of adaptation or the number of points or the -c profile, and see if it works then. (ie. try creating a lower quality/resolution profile to feed into -c.) At a worst case you might have to change the algorithm to something that is guaranteed to work. Graeme Gill.
