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.
