I nuked build/ and it persistent.  I was on cython 0.29.24 but I just updated to 0.29.28.  Looks like I got past that, now I'm having unyt issues since unyt needs an old SymPy.  So maybe I'm past that crash.  Going to downgrade some packages to see if I can finish building.

No, I have not ever seen this.  This is odd.  It strikes me as
entirely possible that it's either using an old version of the
generated code that needs to be re-run (maybe?  That I'm not sure
about) or possibly it's getting the wrong includes.  This is
definitely new to me!  Which version of Cython?
