+Arm64 fails to run a binary which runs OK on real hardware
+
+This binary:
+
+http://oirase.annexia.org/tmp/test.gz
+
+runs OK on real aarch64 hardware.  It is a statically linked Linux binary which (if successful) will print "hello, world" and exit cleanly.
+
+On qemu-arm64 userspace emulator it doesn't print anything and loops forever using 100% CPU.
+
+----
+The following section is only if you wish to compile this binary from source, otherwise you can ignore it.
+
+First compile OCaml from:
+
+https://github.com/ocaml/ocaml
+
+(note you have to compile it on aarch64 or in qemu, it's not possible to cross-compile).  You will have to apply the one-line patch from:
+
+https://sympa.inria.fr/sympa/arc/caml-list/2013-12/msg00179.html
+
+    ./configure
+    make -j1 world.opt
+
+Then do:
+
+    echo 'print_endline "hello, world"' > test.ml
+    ./boot/ocamlrun ./ocamlopt -I stdlib stdlib.cmxa test.ml -o test
+    ./test
