## 解决方案

1. **** (90% 成功率)
   ```
   Run tests with a single worker to isolate the issue: `pytest -p no:xdist` or `pytest -n 0`
   ```
2. **** (70% 成功率)
   ```
   Use `pytest --timeout` to detect hanging tests and reduce memory usage, or debug with gdb to find the crash location.
   ```

## 无效尝试

- **** — More workers may increase memory pressure and exacerbate the crash, not fix the underlying issue. (80% 失败率)
- **** — The crash is likely reproducible and indicates a serious bug; ignoring it leads to unreliable test results. (90% 失败率)
