[issue38081] Different behavior of os.path.realpath('nul') in 3.7 and 3.8

[Александр Семенов]

Александр Семенов <iamsav at gmail.com> added the comment:

It breaks setuptools.sandbox.DirectorySandbox.__init__() with default param 'exceptions' which includes os.devnull and calls os.path.realpath() on it.
So, many distributions crashes.
