------------------------+----------------------------
Got `AssertionError` when constructing `Polyhedron` from an
H-representation that has unusual base_ring and is infeasible,
{{{
sage: Polyhedron(ieqs=[(-sqrt(2),1,1),(0,-1,-1)])
AssertionError
sage: Polyhedron(ieqs=[(-sqrt(2),1,1),(0,-1,-1)], base_ring=AA)
AssertionError
}}}
whereas the following works well.
{{{
sage: Polyhedron(ieqs=[(-1.414,1,1),(0,-1,-1)])
The empty polyhedron in RDF^2
sage: Polyhedron(ieqs=[(sqrt(2),1,1),(0,-1,-1)])
}}}
