+This test demonstrates a bug in Dune's separation compilation of JSOO.
+`std_exit.cmo` wasn't being linked in the end, so the `at_exit`
+hooks didn't run and the channels weren't flushed.
+
+Setup fixtures:
+
+  $ echo "(lang dune 3.17)" > dune-project
+  $ echo 'let () = print_string "bla"' > main.ml
+  $ cat >dune <<EOF
+  > (executable
+  >  (name main)
+  >  (modes wasm))
+  > EOF
+
+Test without separate compilation:
+
+  $ dune build --profile=release ./main.bc.wasm.js
+  $ node _build/default/main.bc.wasm.js
+  bla
+
+Test with separate compilation:
+
+  $ dune build --profile=dev ./main.bc.wasm.js
+  $ node _build/default/main.bc.wasm.js
+  bla
+
+The result should be the same
