Well, it shouldn't be a problem. Suppose you want to fit something like "y
= a * x^8" or "y = a * sin(x)". There's no other way, you must use
multifit. 

I really think it may be a bug, since the fitted parameter is actually
correct despite the error message (at least in the cases that I tested).

Please someone help ! ;^)
