Latest 3.10-slim-bullseye fails on Macbook M1 with Rosetta emulation #792

This is not just 3.10-slim-bullseye. It happens for alpine, non-slim and different Python versions. The Sometimes I get a seg fault instead of a rosetta error. |
|
I can't reproduce with QEMU's emulation, so this has to be a bug in Rosetta -- does anyone know where would be an appropriate place to raise/file that? |
|
Before sending feedback to Apple, I think there's one more test to do: execute an x86_64 binary with similar modifications directly on an ARM-based Mac, without Docker. If that test passes then it may be a Docker issue or a Virtualization.framework issue. If that test fails, it is a Rosetta issue. (This is not my area of expertise at all so I have no idea how to do that) |

Nice idea @rik. Unfortunately macOS doesn't use ELF. It uses the Mach-O format1.
It turns out what I was seeing in the Rosetta error message was the first four bytes of an ELF, which are the ELF magic number Footnotes |

Using Dockerfile
# syntax = docker/dockerfile:1
FROM debian:bullseye
SHELL [ "/bin/bash", "-c", "-x" ]
RUN <<END_RUN
apt-get update
apt-get install -y --no-install-recommends gcc libc6-dev patchelf elfutils
rm -rf /var/lib/apt/lists/*
END_RUN
RUN <<END_RUN
cat <<END_OF_C >hello.c
#include <stdio.h>
int main() {
printf("Hello world\n");
}
END_OF_C
gcc -o hello hello.c
./hello
patchelf --print-rpath hello
patchelf --set-rpath '$ORIGIN/../lib' --output patched-hello hello
patchelf --print-rpath patched-hello
patchelf --remove-rpath patched-hello
patchelf --print-rpath patched-hello
diff -u <(eu-readelf -h -d hello) <(eu-readelf -h -d patched-hello)
eu-readelf -l hello
eu-readelf -l patched-hello
./hello
./patched-hello
END_RUN
docker buildx build --platform=linux/amd64 --progress=plain .

@jimnicholls Thank you very much for working on this. I've just confirmed it fixed the issue for me with the latest tag. |

Description
I am using Python image with amd64 platform flag on an arm64 host with a recent experimental feature from Docker : Rosetta emulation.
Recents changes #785 and #790 appear to have broken latest 3.10-slim-bullseye tag
