Follow-up Comment #1:

I don't think the patch is correct ... it may well fix the problem, but only
at the expense of introducing a memory leak as it fails to release cells in
the region between _numCols and _maxCols.



You don't say where/how the crash happens ... but I assume it's a problem
with a cell being released too many times for some reason (otherwise I don't
see how leaking cells would fix it) ... but I think the extra release of the
cell is happening elsewhere.



Please could you post a short test program demonstrating the problem, and I
will attempt to locate where things are going wrong and fix it.
