Nothing prevents overflow here and in other places.
Actually once you set span a little greater than 1 billion (actually >= 2^30) we get overflow somewhere else (may be in appendColumn()) and span value in m_columns becomes invalid.


So yes, there is problem.
I'd say that all cells locations arithmetic should be done using unsigned just because this seems logical. But even in this case there still place for overflow.

I'm not sure how to solve this, except of may be adding some limitation on "span" value and number of columns, like maxColSpan=10000 and maxColCount=100000. Alternative approach is using longer number, or even number with unlimited precision. But I don't think that we should go so far.

In any case, this sounds as separate enhancement, unrelated with this bug.
Do you want me open new one?
