Description
sage: from sage.rings.asymptotic.growth_group import GrowthGroup sage: A = GrowthGroup('QQ^x * x^ZZ'); A sage: cm = sage.structure.element.get_coercion_model() sage: E = GrowthGroup('ZZ^x * x^QQ') sage: cm.record_exceptions() sage: cm.common_parent(A, E) Growth Group QQ^x * x^QQ sage: for t in cm.exception_stack(): ....: print t
brings up
Traceback (most recent call last): ... CoercionException: Infinite loop in action of Growth Group QQ^x * x^QQ (parent <class 'sage.rings.asymptotic.growth_group_cartesian.UnivariateProduct_with_category'>) and Growth Group ZZ^x * x^QQ (parent <class 'sage.rings.asymptotic.growth_group_cartesian.UnivariateProduct_with_category'>)!
It is caught, so it does not make a problem at all, but IMHO shouldn't be there.
