Comment (by pbruin):
It seems to me that the function `SeriesToContFrac` in Dokchitser's
`computel` program is affected by some numerical instability, so that the
above rounding fix in PARI leads to wildly different output of this
function for the same input. It is probably possible to solve (or at
least diminish) the problem by increasing the variable `asympdigits` in
the script.
