Go binaries panic with "mmap errno 9" on qemu-user.

root@nofan:/# cat hello.go

import "fmt"

func main() {
    fmt.Println("hello world")
}

Tested with qemu from git master with Debian unstable for armel.

Same binaries work fine on real hardware.

[Peter Maydell]

With current QEMU (and in particular with 4.1.0 rc3 or later with commit
5bfce0b74fbd5d5308 that fixes sigaltstack) go binaries work OK. I think
we must have fixed this mmap issue  at some point between when this bug
was reported and now (or possibly the go runtime was made a bit more
forgiving of QEMU's eccentricities).

Oh, that's interesting. I will verify this and if it indeed works, I
will enable Go binaries for sh4 in Debian.

Thanks a lot for the update!

I haven't tested sh4 specifically, but arm (subject of this bug report)
definitely works, as does arm64.

I can confirm that the issue has been resolved on arm. Unfortunately, on
sh4, the Go binaries are still crashing, albeit differently now. I
verified that they work fine on real sh4 hardware.

Could you file a separate bug for the sh4 case, then, please (with repro
instructions)?

[Thomas Huth]

I'm marking this bug as "fix released" now since the Arm problem has
been fixed. If there is something else to do for sh4, please open a new
bug as suggested by Peter.
