Hello.
Somewhat recently gap broke on my machine. Now I get this:
```

Would be nice the "reduce" method handle the Integer 0
It is not really a bug but one often built polynomials from Integer "0"
```
FreeA. = FreeAlgebra(QQ, implementation='letterplace')
I = FreeA*…

the following example fails (at least in M2 1.6)
```
R = ZZ[x,y,z]
I = ideal(17*x*z+10*x-43,41*x*y-16*x,47*z^2-2*z)
J = ideal( 34*x-16,-2*y*z,-20)
Q = quotient(J, I)
gQ = quotient(ideal gens gb J,i…

This should work:
```
sage: R. = PolynomialRing(GF(127),10)
sage: I = sage.rings.ideal.Cyclic(R,6)
sage: gb = I.groebner_basis('magma:GroebnerBasis', deg_bound=4)
```
The culprit is that Polynomia…

There is a problem where cached function report problematic file information. Consider
