[py3.13] rustworkx: `python: ./Include/internal/pycore_object.h:268: _PyObject_Init: Assertion '_PyType_HasFeature(typeobj, Py_TPFLAGS_HEAPTYPE) || _Py_IsImmortal(typeobj)' failed.` #4311

Bug Description

Here's another problem that I've seen with a subset of rustworkx. This time I've confirmed that the issue happens both with a debug build made using Python 3.13 and a wheel built using Python 3.8 (i.e. the stable ABI).

The error is:

python: ./Include/internal/pycore_object.h:268: _PyObject_Init: Assertion `_PyType_HasFeature(typeobj, Py_TPFLAGS_HEAPTYPE) || _Py_IsImmortal(typeobj)' failed.
Fatal Python error: Aborted

Steps to Reproduce

Build Python 3.13 --with-assertions.
git clone https://github.com/Qiskit/rustworkx/
Build and install rustworkx and pytest.
python -m pytest tests/digraph/test_adjacency_matrix.py::TestDAGAdjacencyMatrix::test_graph_to_digraph_adjacency_matrix -s

Additional Info

According to bisect, it's caused by python/cpython@c32dc47. CC-ing @markshannon, since I suspect this change actually broke the stable ABI (presuming PyO3 implemented it correctly).

The text was updated successfully, but these errors were encountered:

davidhewitt · 2024-07-05T09:36:28Z

It looks to me like what's likely happened is a PyO3 extension using the 3.8 stable ABI has called Py_INCREF on the PyExc_TypeError type object, and that's caused the offending assertion to fail.

Very similar situation to #4309 (comment), I think. The understanding there is that PyO3 is doing the correct thing.

mgorny · 2024-07-05T15:16:38Z

I'm a bit worried how many similar issues are we going to discover in 3.13…

mgorny · 2024-07-07T17:05:23Z

Interesting enough, this seems to happen on a code path specific to Python < 3.12. If I use abi3-py312 instead, I don't get a crash anymore.

davidhewitt · 2024-07-09T06:54:25Z

That sounds correct. From Python 3.12 the stable ABI was switched to use a function call to do reference counting (Py_IncRef) rather than directly modify reference counts in extensions. The function call will respect immortality.

One option we have is to change our implementation of the stable ABI for older versions to also use the function call. This will come at a performance cost, but given that those projects will hit that performance cost anyway when they upgrade to minimum version of 3.12 we'd just be bringing that change forward.

(That said, CPython is currently failing assertions against the older stable ABI so others in the C/C++ ecosystem will likely hit this too.)

mgorny · 2024-07-09T09:40:35Z

Given no reply from the committer I've CC-ed here, I'll file a bug report on the CPython bug tracker now.

mgorny · 2024-07-09T09:47:53Z

Filed python/cpython#121528.

mgorny · 2024-07-10T17:13:54Z

@davidhewitt, could you take a look at python/cpython#121528 (comment) and below, please? I'm not sure if it's because my reproducer isn't accurate, or PyO3 actually did something outside of specified stable ABI.

davidhewitt · 2024-07-10T18:35:35Z

Sure, commented on there.

davidhewitt · 2024-08-16T21:10:14Z

Looks like the upstream issue is resolved, so I will close here.
