All three test runs showed failures in the same set of tests, such as
random-intersections, fill-rule, dash, caps, clip, bug-84115...

My guess would be that these new failures are caused by this patch:

commit 2de69581c28bf115852037ca41eba13cb7335976
Author: Massimo Valentini <mvalentini at src.gnome.org>
Date:   Sun Oct 19 09:19:10 2014 +0200

    tor-scan-converter: can't do_fullrow when intersection in row +
    0.5subrow

    the active edges list must be left sorted at the next possible use
    and since full_row does not deal with intersections it is not usable
    when there is an intersection in the top half of the next row first
    subrow
