[Gdal-dev] problem about "RasterI O"

[Ray Gardener]

Two things:

Your code should read:

  GUInt32* pData;
  pData = (GUInt32*) CPLMalloc(sizeof(GUInt32)*nXSize*nYSize);

just to be safe (i.e., LONG on your machine may be 64 bits).

Second, just set a debugger breakpoint on the call to
CPLMalloc and step into it.
