[issue33047] "RuntimeError: dictionary changed size during iteration" using trace.py module

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

I copied the three lines into a file, deleted '> ', added  print('done'), and saved.  I ran the file, on Windows 10, with installed 2.7, 3.5, 3.6, and repository 3.6, 3.7, and 3.8.  No failures.
  
Adrien, please retest by copying what you posted, and if you still get a failure, upgrade to 3.6.4 and try again.  Unless we see a failure on another machine, this should be closed.
