This is https://github.com/matplotlib/matplotlib/pull/3811 which is 
fixed and merged.  Should it still be an issue?

Ugh, I tried this same example on my ubuntu box and it works. I
update this
diagnosis to "scatter is broken on windows since removing PyCXX";
note that I
do not get a traceback with the code below if I replace "scatter"
with "plot".

Being that windows devs are scarce, I'll be digging into this more.  I
certainly welcome any clues as it seems very bizarre to me so far.
