Stable ABI: `Objects/bytesobject.c:122: PyBytes_FromStringAndSize: Assertion '_Py_IsImmortal(op)' failed.`

Crash report

What happened?

While testing qiskit, I've found another crash in the stable ABI with 3.13. I've confirmed it with CPython 3.13 as of 3ab8eaf.

To reproduce:

pip install qiskit pytest ddt
git clone https://github.com/Qiskit/qiskit/
cd qiskit
mv qiskit{,~}  # hide the non-compiled package
pytest -s test/python/circuit/library/test_blueprintcircuit.py::TestBlueprintCircuit::test_global_phase_copied

Python traceback:

[ZeroIntensity]

I think this should get investigated by PyO3 first, but at a very quick glance, this looks like it could be a problem with the latin 1-byte strings string interning. Possibly related to #122303.

[ZeroIntensity]

Actually, scratch that: I think it's caused by #120520, which allows interned strings to be mortal, so this might just be a precondition that wasn't updated. Do any other bugs occur if you remove that assertion?

[mgorny]

If you mean that specific test, it passes then. However, the test suite in general triggers another failed assertion:

python: Objects/typeobject.c:5660: fini_static_type: Assertion `_Py_IsImmortal((PyObject *)type)' failed.

But I suppose that's a separate problem to report, and ideally I'd try to pinpoint it better first.

[ZeroIntensity]

I'm guessing something changed recently with immortality, but this could be a PyO3 issue depending on what APIs they're using. Has this been reported to them yet?

[mgorny]

We've reported similar issues (i.e. regarding immortality changes in 3.13) to them before, and the conclusion was that since they're using the stable ABI here, CPython needs to preserve compatibility for the sake of extensions built against earlier versions. PyO3 already have done a major fix that causes these issues to disappear, but the existing extensions will continue crashing until new wheels are built against newer PyO3 versions (and things move slowly). I've CC-ed David Hewitt here for completeness, but it feels weird to report issues if I know that they are fixed on PyO3's end — so I'm filing them on this end for completeness.

[ZeroIntensity]

Is PyO3 itself using the stable ABI, or just qiskit? I'm wondering if they're using some private API regarding immortality that changed recently.

[ZeroIntensity]

@picnixz this is interpreter-core as well.

[davidhewitt]

I assume this is indeed one of the cases already "fixed" on PyO3's side by moving to use FFI calls for all refcounting with the stable ABI - as qiskit is currently still on PyO3 0.21 https://github.com/Qiskit/qiskit/blob/76eb568c14f79ab9dad17d61c49380a5c7ef5e85/Cargo.toml#L33

(We released the fix in 0.22.2; I think based on PyO3/pyo3#4428 the qiskit team is working on updating to PyO3 0.22)

The main point I see here is that assertions of immortality are broken when compiling against stable ABI versions which used inline reference counting i.e. before immortality was added and the stable API switched to use function calls.

[mtreinish]

I think based on PyO3/pyo3#4428 the qiskit team is working on updating to PyO3 0.22

We are planning to upgrade to pyo3 0.22.x asap, but we're blocked on the next rust-numpy release before we can really start the process as we rely fairly heavily on numpy.

[encukou]

The string interning changes involve PyUnicode (str); this report shows PyBytes (bytes).
For the reproducer, I also needed cmake and https://github.com/symengine/symengine

---

Yes, this looks like another issue like #118997 and #121528. Turns out assert(_Py_IsImmortal) is dangerous, and when this assert was added (#107605 -- cc @brandtbucher) we didn't have _Py_IsImmortalLoose yet.

I guess next week I'll audit all the uses of _Py_IsImmortal.

[vstinner]

To reproduce: pip install qiskit pytest ddt
