[New-bugs-announce] [issue44581] Interpreter can execute quickened opcodes in tracing mode

[Mark Shannon]

New submission from Mark Shannon <mark at hotpy.org>:

This breaks a key invariant of PEP 659.

Inserting `assert(cframe.use_tracing == 0);` at the top of all quickened instructions results in several failures when running the test suite.
