In `src/sage/schemes/toric/divisor.py`, there is:
{{{
class
ToricRationalDivisorClassGroup_basis_lattice(FreeModule_ambient_pid):
def __init__(self, group):
# ...
super(ToricRationalDivisorClassGroup_basis_lattice,
self).__init__(
ZZ, group.dimension())
}}}
(note the `ZZ`)
However, in `src/sage/schemes/toric/divisor_class.pyx`, there is
{{{
cdef class ToricRationalDivisorClass(Vector_rational_dense):
}}}
So, do we want rationals or integers? This causes segfaults when improving
vectors in #17562.
