Not in the published divide-and-conquer algorithm, no.

There was a bug in the implementation of the new basecase algorithm, which
was not published, nor very important. On most machines it was switched
off. And even on the machines where it was used (with the exception of
itanium where it seemed to be used a lot), it was only used for *very*
small operands.

I'm slightly surprised that there was a bug, since I literally ran tests
for hours to check it. But it's simply not worth debugging to find the
exact cause. The whole thing can be ditched without anyone really noticing
anything, performance-wise.

If I had more time I'd be more thorough with the postmortem, but right at
the moment there are infinitely many, infinitely more important things I
must be getting on with.

Bill.
