[4.13] ocamlopt fails with "Fatal error: Liveness.fundecl" #10520
Description
Trying to install owl-base.1.0.1 using the latest OCaml 4.13 (7a182bd) results in the following fatal error:
# (cd _build/default && /home/opam/.opam/4.13.0+trunk/bin/ocamlopt.opt -w -40 -g -I src/base/.owl_base.objs/byte -I src/base/.owl_base.objs/native -intf-suffix .ml -no-alias-deps -o src/base/.owl_base.objs/native/owl_maths_quadrature.cmx -c -impl src/base/owl_maths_quadrature.ml)
# >> Fatal error: Liveness.fundecl:
# pp/65
# Fatal error: exception Misc.Fatal_error
Looking at the commits since the last check, I suspect it might be an issue in #10039 (backported in the 4.13 branch)
