py2exe crashes on simple program

[John Nagle]

  I'm trying to create an executable with py2exe.
The program runs fine in interpretive mode.  But
when I try to build an executable, py2exe crashes with
an assertion error. See below.

  This is an all-Python program; no binary modules
other than ones that come with the Python 3.5.2
distribution. Running "python setup.py bdist"
works, so "setup.py" is sane.  What's giving
py2exe trouble?

U:\>python setup.py py2exe
running py2exe
running build_py
Building shared code archive 'dist\library.zip'.
