Comment (by pbruin):
I can reproduce this inside GP 2.7.1 (patched version of this ticket) on
ARM using the following commands (also adapted from `dokchitser.log`):
{{{
read("local/share/sage/ext/pari/dokchitser/computel.gp");
default(realprecision, 19);
conductor = 37;
gammaV = [0, 1];
weight = 2;
sgn = -1;
Lpoles = [];
Lresidues = automatic;
e = ellinit([0, 0, 1, -1, 0]);
a(k) = ellak(e, k);
initLdata("a(k)", 1.0);
v = Vec(Lseries(10.0, , 5));
print(v)
}}}
One gets the correct answer after replacing 19 by 20 in the second line,
presumably because this increases the precision by one word.
