Another integral affected by this change:
(1) -> integrate(1/sqrt(1 + b*sec(x))^3,x)
>> Error detected within library code:
RadicalFunctionField: curve is not irreducible
It worked in 1.2.7.
A simple change can make most of these problems go away,
but as discussed before, there's a better
Another integral with exact same problem:
(1) -> integrate((k*x^2 - 1)/((a*k*x + b)*(b*x + a)*sqrt((1 - x^2)*(1
- k^2*x^2))), x)
>> Error detected within library code:
catdef: division by zero
Under FriCAS 1.2.7, this integral returns after 1 minute.

I misunderstood a little, my point is:
1) The default value of nn should not be 1.
2) We should use "1+random(nn)" in this case to avoid 0.
