Hello,

Builing httptools 0.6.4, I see:

```

```

This happens using the systemt-provided llhttp and http-parser libraries. Python is at 3.10.7, while the direct inputs are:
```
dependencies: http-parser@2.9.4-1.ec8b5ee llhttp@9.1.3 python-cython@0.29.32 python-pytest@8.3.3
```

Empieza con tests/test_parser.py y ejecuta TestResponseParser.test_parser_response_leninent_headers_1 usando las versiones indicadas de Python, http-parser y llhttp. Investiga por qué no se genera HttpParserError con las bibliotecas proporcionadas por el sistema; el trabajo estará terminado cuando se haya resuelto el comportamiento de la prueba o se haya hecho explícita la expectativa de compatibilidad.
