There is a bug in allvalues in Release 3, patchlevel 3. Everything works well on polynomials that have at least two diﬀerent roots:
But on polynomials \((x-k)^n\) which are not expanded and on \(x^n\), Maple fails and only returns the root one time instead of n times:
So you can work around the bug by simply expanding the polynomial. But there still remains the faulty case \(x^n\).
Is this bug corrected in Release 4 or Release 5?
The same behaviour up to Maple 8 (U. Klein)
