The Guile developers chose a rather naive way to decide if the cache is stale: If it’s newer than the source file then it’s OK. That means that if GnuCash version X is run for the first time on a particular machine after the date that a Scheme file is changed in git (which date is preserved in the tarball) then Guile won’t recognize the new file and will continue to use the cached compilation with predictable results.
