% ./python.exe namedexpr.py Assertion failed: (e->kind == Name_kind), function symtable_extend_namedexpr_scope, file symtable.c, line 1877.zsh: abort ./python.exe namedexpr.pyThis is on a debug build; on a release build presumably it will segfault or trigger UB somewhere.
I'll have a fix soon.
On 3.11 the reproducer instead fails withTypeError: '<' not supported between instances of 'int' and 'str' for me. Not sure what's up with that; the code that should trigger the crash is the same on 3.11 and main.
