Details:

Hi all,

Using the latest snapshot version of the Mapping package, I get an out of
memory error with shapewrite, when trying to write a large file.

The out of memory error comes from line 158:


    ## "Point" need not have a BoundingBox field => add a dummy if not found
    if (stype == 1 && ! ismember ("BoundingBox", fldn))
      
      [shp.BoundingBox] = deal (repmat (zeros (2, 2), numel (shp)));

    endif


The error can be avoided by changing the line to:


[shp.BoundingBox] = deal([0,0;0,0]);
