[pdal] 'PDAL: vector<T> too long' error when Using writers.gdal with bounds option in PDAL 2.3.0

[Andrew Bell]

I'm guessing you're on a 32-bit windows system. For all practical purposes
this is an "out of memory" error. In order to process the data the GDAL
writer needs to create at least one raster that handles your bounds /
resolution * sizeof(data_type). Windows is reporting that this memory is
unavailable. If you going to process large amounts of data, you should
consider using a 64-bit system.

Other than this, I have no ideas. The GDAL writer has been used
successfully with very large datasets and rasters, so I'm not sure what
else the problem might be.
