I think what I'm seeing here is a RunTimeError caused by a recursion depth
exceeded on a call to .__invert__ for a ComplexIntervalField element.
If I increase the precision enough, I don't see this anymore. Is this a bug
or should I just try/except for RunTimeError and increase the precision in
what I'm trying to do?
Here is a piece of code that generates the error. Sorry I couldn't isolate
it further but it is sensitive to the particular inputs.
P.<x,y>=ProjectiveSpace(QQ,1)
H=End(P)
f=H([6567*x^5 - 34786555*x^3*y^2 + 247565*y^5,14*x^3*y^2])
m=matrix(QQ,2,2,[239487,2345,123412345,-23452345])
f=f.conjugate(m)
K = ComplexIntervalField(prec=128)
fK = f.change_ring(K)
PK = fK.domain()
for p,e in
f.dynatomic_polynomial(1).subs({y:1}).univariate_polynomial().roots(ring=K):
Q=PK(p,1)
F.jacobian()(tuple(Q.dehomogenize(1)))
