crash when compiled with nuitka

I got the following crash trying to compile my app with nuitka. I'm guessing this is something they need to fix, but I thought I would share it here in case it helps:

Traceback (most recent call last):
  File "C:\cvs\itas\IT20FB~1\ITASPI~1.DIS\trio\_core\_run.py", line 2003, in unrolled_run
  File "C:\cvs\itas\IT20FB~1\ITASPI~1.DIS\trio\_core\_run.py", line 1388, in spawn_impl
AttributeError: 'NoneType' object has no attribute 'f_locals'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\cvs\itas\IT20FB~1\ITASPI~1.DIS\ItasPinClientPortal.py", line 3253, in <module>
  File "C:\cvs\itas\IT20FB~1\ITASPI~1.DIS\trio\_core\_run.py", line 1887, in run
  File "C:\cvs\itas\IT20FB~1\ITASPI~1.DIS\trio\_core\_run.py", line 2202, in unrolled_run
trio.TrioInternalError: internal error in Trio - please file a bug!

Python 3.8.5
Trio 0.16.0
Quart 0.12.0
Quart-Trio 0.5.1
Nuitka 0.6.9.2

Start with the traceback locations in trio/_core/_run.py, especially unrolled_run and spawn_impl, and compare the reported Python, Trio, Quart, Quart-Trio, and Nuitka versions. Reproduce the crash with the provided compilation setup; done means identifying whether the failure belongs in Trio or Nuitka and adding a confirmed regression case if a Trio change is required.
