You compile your tests case with ocamlopt which produce cmx file. Unlike cmo
file, a cmx file does depend on the cmxs of the modules it use. The result of
ocamldep will tell you about that. The reason for that is a .cmx files carries
information for cross-module optimization, once recompiled, its visitor modules
should change correspondingly. 

There should be some FAQ somewhere contains more information, you may just look
up.
