This is a known issue in the new code for Bessel(nu,z) function when
|z| -> oo committed yesterday. It's been caught up during the night by
our CI code, see
http://pari.math.u-bordeaux.fr/buildlog.html
("BUG"'s all over the place); the cause is known as well, I'm working on
a fix right now. Stay tuned :-).
Cheers,
