Description
The following calculation runs "forever":
sage: g = QQbar(-27/4)^(1/7) sage: (nf, elems, mor) = number_field_elements_from_algebraics([sqrt(2), sqrt(-1), g]) sage: nf3.<n> = NumberField(nf.polynomial(), embedding=mor(nf.0)) sage: QQbar(-1/108*n^12) == -g
A fast path in qqbar.py's cmp_elements_with_same_minpoly
should trigger but doesn't.
