Comment(by sjamaan):

 syntax-rules is a macro. Its expansion includes renamed identifiers for
 "length", among others.

 But this renaming doesn't appear to work properly; if there are imported
 procedures with the same name, those are used instead of the ones from
 library.scm.  So yes, I think the problem is "that the expansion of a
 syntax-rules contains expander-specific code that captures identifiers".

 I think this has something to do with the fact that it's a macro-
 generating macro. I will try to come up with a simpler testcase.
