In Python 3.9.0, running
compile('A.\u018a\\ ', '<string>', 'single')
raises
SystemError: <built-in function normalize> returned a result with an error set
This is obviously invalid syntax, but it would still be nice to raise SyntaxError for that and the SystemError may be symptomatic of a bug. Unfortunately I have no insight to offer beyond this hand-minimised reproducer :-/

Wow! Thanks and congrats on the super-fast fix :-) FYI Paul Ganssle has recently [1] started to work on adding property-based tests to CPython CI [2]. Once Paul gets the stubs and first set of tests working, I'll start moving the others over from my demo repo [3] to CPython master so we catch this kind of bug earlier in future.
