#3265 gcfactor(0) -> division by zero

[Gilles Schintgen]

gcfactor(0);
Maxima encountered a Lisp error:
Condition in MACSYMA-TOP-LEVEL [or a callee]: INTERNAL-SIMPLE-ERROR: Zero divisor.
Automatically continuing.
To enable the Lisp debugger set debugger-hook to nil.

This is with maxima 5.37.2 (Ubuntu 16.04).
Expected result: 0 (or a more precise error message, but not an uncaught internal lisp error).

Tested in 5.42. Still broken.

[Kris Katterjohn]

Thank you for the report. I've fixed this with commit [e0298c]:

(%i1) gcfactor (0);
(%o1) 0

By the way, it looks like this was broken back in Maxima 5.0 as well.
