pyo3 tests fail with exit code -11 even though all tests pass

[clin1234]

I'm trying to inspect pyo3 CI build failures stemming from 3.14 (both regular and free-threaded versions) on Ubuntu, macOS, and Windows. The failure stems from this section:

      - name: Test python examples and tests
        shell: bash
        run: nox -s test-py
        env:
          CARGO_TARGET_DIR: ${{ github.workspace }}/target

      - uses: dorny/paths-filter@v3
        if: ${{ inputs.rust == 'stable' && !startsWith(inputs.python-version, 'graalpy') }}
        id: ffi-changes
        with:
          base: ${{ github.event.pull_request.base.ref || github.event.merge_group.base_ref }}
          ref: ${{ github.event.pull_request.head.ref || github.event.merge_group.head_ref }}
          filters: |
            changed:
              - 'pyo3-ffi/**'
              - 'pyo3-ffi-check/**'
              - '.github/workflows/ci.yml'
              - '.github/workflows/build.yml'

Output:

[RonnyPfannschmidt]

pytest itself has exit codes between 0 and 5 - its unclear where you value is from

[The-Compiler]

Negative exit codes are always signals - in this case, signal 11, better known as SIGSEGV / segmentation fault.

[The-Compiler]

The culprit here won't be in pytest, but in either an extension module with native code (e.g. C/C++) triggering a segfault on exit, or possibly something in CPython itself.

The first thing I'd do is running python -X faulthandler -m pytest so you hopefully get a Python stracktrace (even on exit, where pytest's own faulthandler support is already disabled again).

If that doesn't tell you enough, you'd need to get a Python debug build (ideally configured with --with-pydebug), which might already tell you more as various additional assertions are enabled.

With that, you could then get a C/C++ stacktrace of what's going on, with something like gdb -ex r --args python3 -m pytest, and then using bt at the (gdb) prompt once it crashes.

Update: after manually installing the dev deps with pip and copying over the generated pyo3_pytests module, progress:
