Observed the same here... (details of the environment at the end of the post)

Just building a hello world is good enough to crash go 3 times out of 4:

--8<---------------------------------------------------------------------
ubuntu@qemu:~$ cat <<EOF > hello.go
> package main
> 
> import "fmt"
> 
> func main() {
>   fmt.Println("Hello")
> }
> EOF

--8<---------------------------------------------------------------------

If I build it with affinity set to a single CPU, all is fine:

ubuntu@qemu:~$ taskset -c 1 /usr/bin/qemu-aarch64-static /usr/lib/go-1.10/bin/go build
ubuntu@qemu:~$ taskset -c 1 /usr/bin/qemu-aarch64-static /usr/lib/go-1.10/bin/go build
ubuntu@qemu:~$ taskset -c 1 /usr/bin/qemu-aarch64-static /usr/lib/go-1.10/bin/go build
ubuntu@qemu:~$ taskset -c 1 /usr/bin/qemu-aarch64-static /usr/lib/go-1.10/bin/go build


But with the go build going multithreaded, all sorts of hells break loose:

--8<---------------------------------------------------------------------
ubuntu@qemu:~$ /usr/bin/qemu-aarch64-static /usr/lib/go-1.10/bin/go build
fatal error: exitsyscall: syscall frame is no longer valid
fatal error: malloc deadlock
panic during panic

runtime stack:

	/usr/lib/go-1.10/src/runtime/panic.go:690 +fatal error: unexpected signal during runtime execution
0x178stack trace unavailable
--8<---------------------------------------------------------------------

or this:

--8<---------------------------------------------------------------------
ubuntu@qemu:~$ /usr/bin/qemu-aarch64-static /usr/lib/go-1.10/bin/go build
fatal error: unexpected signal value
panic during panic
