Gröbner basis + complete_reduction=false = SIGSEGV

The following snippet

```julia
using AlgebraicSolving
R, (x,y,z) = polynomial_ring(QQ, ["x","y","z"], internal_ordering=:degrevlex)
I = Ideal([x+2*y+2*z-1, x^2+2*y^2+2*z^2-x, 2*x*y+2*y*z-y])
groebner_basis(I, complete_reduction=false)
```

segfaults on both Linux and macOS. The error does not occur when `QQ` is replaced by `GF(101)`.
