Comment(by SimonKing):
I started with "manually" testing against three of the doc test errors
that I got with my patch. Two of them fail with Alexander's patch as well:
{{{
sage: P.<x,y,z> = QQ[]
sage: x/0
Traceback (most recent call last):
...
ZeroDivisionError:
}}}
--> The old error message "rational division by zero" has gone.
{{{
sage: (x*y).is_monomial()
True
sage: (2*y).is_monomial()
False
}}}
--> That's better than my patch, where these return 1 and 0.
{{{
sage: (x+y^2^30)^10
x^10
}}}
--> That should result in an overflow error.
I didn't analyse the segmentation faults.
