The loop processing segments sa and sb in clean_parrallel() wraps back
to the first segment, and the bug resets the number of points based on
the last segment seen (ie sa back to "0"), not the maximum number of
points added to the output group. (see debug output in bug history)

(clean_parallel() is in lib/vector/Vlib/buffer.c)

Hopefully that is enough of a clue for someone to find a solution. I
won't have any time to work on it for the next week or two, but would
like to see this fixed and tested for the 6.2.0 release.
