[Maxima] gcd problem

Hi all again,
I just want to point out that the 2 problems
I reported seem very unrelated to me.
- The gcd problem is related to some sort
of overflow due perhaps to an
(unreasonable for me in a "symbolic system")
limit of the size of expoennts.
Remark: IMHO from a symbolic system most people expect
arbitrarily long integers.
- The factor problem seems very different:
The example I showed features no big numbers
and the error message is a different one.
