New submission from Giampaolo Rodola':

>>> import ctypes
>>> path = 'C:\\Python35-64\\vcruntime140.dll'
>>> cfile = ctypes.CDLL(path)
>>> cfile._handle
140736170229760
>>> ctypes.windll.kernel32.FreeLibrary(cfile._handle)
Traceback (most recent call last):
    ctypes.windll.kernel32.FreeLibrary(cfile._handle)
ctypes.ArgumentError: argument 1: <class 'OverflowError'>: int too long to 
convert

Everything is fine on 32-bit.
