can you attach the test_utils.py reproducer.
I tried rebuilding python-llama-cpp-python and it's tests fine.

from llama_cpp import Llama

model_name = "Mungert/gemma-3-1b-it-gguf"
suffix = "q4_k_s.gguf"

model_instance = Llama.from_pretrained(
    repo_id=model_name,
    filename=f"*{suffix}",  # this will download the quantized model only
    n_ctx=0,
    verbose=5,
    logits_all=True)
response = model_instance(
    prompt="Hi, how are you?",
    stream=False,
    max_tokens=0,
    logprobs=1)
print(response)


This is the minimal reproducer. It downloads real gemma3 model and uses it. I disabled all inference tests in python3-llama-cpp because we didn't have huggingface_hub library, but now that we have it, I should re-enable them.

Actual result:

zsh: illegal hardware instruction (core dumped)  python3 minimal.py

Expected result (with the stack from PyPI)::

This happens to me too on F42.

Hello,

I'm bumping into this bug when running logdetective. Unfortunately the bug doesn't seem to have gone in the fixed version of llama-cpp, I can still reproduce the bug using the snippet from comment 2:

I guess I shouldn't reopen this bug now that it's closed/errata, but rather clone it into a new one, right?
