Intermittent exec format error when building linux/arm64 (alpine 3.15+) on amd64 host

[kevin-lindsay-1]

Is this a bug report, feature (enhancement) request or question? (leave only one on its own line)

/kind bug

Description:

I have a docker container that builds, and commands will randomly fail with exec format error. I can provide this dockerfile upon request.

Steps to reproduce the issue:

Describe the results you received:

Describe the results you expected:

Environment:

• QEMU version: (if you can know it): 7.0.0-7
• Container application: Docker/Podman/Singularity (Leave only one): docker

Output of docker version, podman version or singularity version docker:20.10.17 running with buildx:0.8.2

Additional information optionally: I have tried many different version tweaks, and this error just keeps occurring unpredictably. I'm not 100% sure it's caused by QEMU, but I run this same build on linux/amd64 and it has failed 0% of the time (running in parallel).
