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.
