I suspect that the size of the 5GB file is originally a 64 bit quantity, but gets cast unsafely to a 32 bit size_t to give 1GB.  This is causing the miscalculations.

There is no way to map all of a 5GB file in a 32 bit process -- 4GB is the maximum -- so any such attempt should raise an error.  This does not prevent us from mapping *part* of a 5GB file.
