What did you do?

1. create a simple unit test.

package main

import (
	"fmt"
	"testing"
)

func TestDemo(t *testing.T) {
	fmt.Println("hello world")
}

2. install qemu-user-static on ubuntu24.

          sudo apt-get update
          sudo apt-get -y install qemu-user-static

3. cross build and test the code.

export GOOS=linux
export GOARCH=mips64
go test -v -coverprofile="coverage.txt" -covermode=atomic ./...

What did you see happen?

4. got crash

What did you expect to see?

test success.

ps: go1.21 and go1.23 works fine.

Does this issue also affect 1.23 and 1.24? You mentioned 1.23 is working but 1.22 is broken. Note that only the two most recent versions of Go are supported. https://go.dev/doc/devel/release#policy. We are closing this issue for now, feel free to reopen it if it appears again in a newer Go. 😊

CC @golang/runtime @golang/compiler for visibility.

Is it reproducible with actual hardware, or at least full system emulation? Userspace emulation tends to be not very reliable, especially for less common platforms like MIPS64. Also, userspace emulation is not a supported platform.
