SIGSEGV when building x86_64 Fedora image on ARM64 OSX host

[Serisium]

Howdy, I'm trying to build a Fedora bootc image on my M3 MacBook Pro host. When I run the below command, I quickly see a segfault in the Go runtime. I've tested Fedora 44, 43, and image types anaconda-iso and bootc-installer.

Thanks for taking a look, I'd be glad to test other configurations or give more details.

Machine

14" MacBook Pro.
Apple M3 Pro
18GB Memory
Sequoia 15.6.1

Command

sudo podman run \
	--rm \
	-it \
	--privileged \
	--pull=newer \
	--security-opt label=type:unconfined_t \
	--platform linux/amd64 \
	-v ./config.json:/config.json:ro \
	-v ./output:/output \
	-v /var/lib/containers/storage:/var/lib/containers/storage \
	quay.io/centos-bootc/bootc-image-builder:latest \
	--type anaconda-iso \
	--target-arch amd64 \
	--rootfs ext4 \
	quay.io/fedora/fedora-bootc:44-x86_64

Thanks for the report. I'll try to reproduce this on an M1 Mac Mini I have for testing and get back to you. Regardless of where the issue is, we should't be segfaulting, so I'd love to figure out what's going on here.
