The code is curious, so I'll just quickly answer without studying it
deeply :-) - I guess during the first pass the ++aIter is not accessed
at all.  Then at the end of the 1st pass, it is initialized (aIter =
aRowSpanCells.begin(); at the end), and the we can do ++aIter as we
want...

Could work - but as I did not look well enough at this code, please
don't take it as 'go ahead & clean it up' :-) - some checking of the
history of that file could give you more clues about that I guess.

Thanks for looking into this!

All the best,
