Comment 78 for bug 1700373

Marking xenial-verification-done

I was able to reproduce the compilation crash as described on the ocaml bug in about 30 minutes on my Skylake machine. After upgrading firmware, I have been running for simultanous compilations loops for the last 2 hours with no crash. I will let them continue to run although I don't expect to see any issues.

<Test-case>
Download report.tar.gz from https://caml.inria.fr/mantis/view.php?id=7452 and place in your schroot scratch directory.
$ mk-sbuild artful --arch=amd64
$ schroot -c artful -u root
// Artful was chosen as it contains the required versions of Ocaml for the reproducer.
$ apt install ocaml opam ocaml-findlib m4
$ opam init
$ opam install extprot
$ eval `opam config env`
$ while ocamlfind opt -c -g -bin-annot -ccopt -g -ccopt -O2 -ccopt -Wextra -ccopt '-Wstrict-overflow=5' -thread -w +a-4-40..42-44-45-48-58 -w -27-32 -package extprot test.ml -o test.cmx; do echo "ok"; done
</test-case>

// forgive the test-case for incorrect ocaml-isms, but as I've never developed using it...
