Comment(by felix):

 I think the problem is that `##sys#canonicalize-body` compares the
 starting expressions of bodies with an `eq?` on the result of `lookup`.
 The expansion of `define-record` expands into definitions with a renamed
 version of `define`, and the lookup returns the global toplevel definition
 of `define` which does not compare `eq?` with `'define`. Just a hunch, but
 this must somehow be the reason (this or something similar). Perhaps we
 should use a different lookup routine in this case: just `eq?` comparison
 with the symbol or it's macro-alias (if it exists).
