+Tested with qemu from git master with Debian unstable for armel.
+
+Same binaries work fine on real hardware.
+
+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)?
+
+
+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.
