segfault when creating venv using uv on Apple Silicon CPU with amd64 platform

[daveisfera]

Description

Creating a venv with uv on amd64 platform with an Apple Silicon CPU causes a segfault

Reproduce

1. Create a Dockerfile to install uv and then create a venv:

FROM python:3.14.2-slim-trixie

WORKDIR /usr/src/app

RUN pip install uv==0.9.27
RUN uv venv /usr/src/venv

2. Build the image:

docker build -t uv_segfault --platform linux/amd64 .

3. Observe segfault:

ERROR: failed to build: failed to solve: process "/bin/sh -c uv venv /usr/src/venv" did not complete successfully: exit code: 139

Expected behavior

Would build like it does on an Intel CPU

Additional Info

Works find when building a native image and I tried on an Intel CPU with native, arm/v7 and arm64 and all worked as expected
