Comment (by AlexGhitza):
Thanks for catching this. It actually comes from a bug in Pari:
{{{
? besselj(0, 0)
%1 = 1.000000000000000000000000000
? besselj(0.E-19, 0)
*** besselj: gpow: 0 to a non positive exponent.
}}}
I've reported it upstream, but I will post a patch with a workaround
while we wait.
