Description of issue

I noticed that, only in emulated amd64 homebrew/brew container (or homebrew/ubuntu22.04 or homebrew/ubuntu24.04), gh crashes.

This does not happen with Apple's container or Docker. And doesn't happen in emulated amd64 vanilla ubuntu container either.

So I don't know where this bug originates from. Any ideas?

[Bo98]

Because of complicated bootstrapping reasons (that might not be accurate anymore - will need to see), the gh in the container isn't actually Homebrew's gh so we don't really control that build. Might be worth trying brew install gh, though you might get the same bug.

The underlying bug sounds like this: golang/go#69255, which will be fixed in Go 1.25.4. It sounds like you might be running the container under QEMU so switching to Rosetta could work as a workaround. This will explain why Apple's container and Docker work as they use Rosetta by default.
