* summary: gcd needs improved coersion => [with patch, needs review] gcd
needs improved coercion
Comment:
It is indeed not coercion-related. The computation of the gcd is done in
a loop, from which one exits as soon as a gcd of 1 is obtained (ignoring
the rest of the elements). In the case of elements with denominators
(such as rational numbers or rational functions) this gives rise to the
wrong answers reported above.
The attached trivial patch fixes this so that correct answers are
returned.
