Yes. From the initial bug report for issue 2222 the failed output shows:

Running lilypond...
GNU LilyPond 2.15.25
Processing `snippet-map-1372012142.ly'
Parsing...
Processing `html-inline-no-options.html'
Parsing...
html-inline-no-options.html:16:16: error: GUILE signaled an error for
the expression beginning here
  line-width = #
                (- line-width (* mm  3.000000) (* mm 1))
Unbound variable: line-width

We see that line-width was used before it was defined.
