Comment (by Snark):
Indeed that's what Bill Allombert answered to my bug report in debian: the
pari code is correct, and the computeL code looks like it uses
catastrophic cancellation... hence it should really shoot for more
precision. Either by increasing asymdigits at Peter suggests, or (notice
that the following only solves that one example) change the line in
dokchitser.py which sets the realprecision to {{{prec//3+2}}} to
{{{prec//3+3}}}.
