      Description

        The new macro in sizecalc.h that is supposed to catch the integer multiplication overflow while allocating and reallocating memory for native arrays is too restrictive and limits the amount of memory that can be allocated - especially on the 32-bit systems. Right now the existing functionality that uses this macro does not require such memory allocation but i think we should be proactively defensive in anticipation that this macro might be used in the future for something else that will require large amount of memory allocated at once.
