+This test demonstrates a bug in dune's separation compilation of jsoo.
+std_exit.cmo wasn't being linked in the end, which was causing at_exit hooks not
+being ran and channels not being flushed.
+
+Setup fixtures:
+
+  $ echo "(lang dune 2.6)" > dune-project
+  $ echo 'let () = print_string "bla"' > main.ml
+  $ cat >dune <<EOF
+  > (executable
+  >  (name main)
+  >  (modes js))
+  > EOF
+
+Test without separate compilation:
+
+  $ dune build --profile=release ./main.bc.js
+  $ node _build/default/main.bc.js
+  bla
+
+Test with separate compilation:
+
+  $ dune build --profile=dev ./main.bc.js
+  $ node _build/default/main.bc.js
+  bla
+
+The result should be the same
