+The alternation between the grouped and ungrouped reporting formats for coveredLines accommodates the
+difference between symex-driven-lazy-loading (which currently causes jbmc to use the grouped format)
+and normal loading (which uses the ungrouped format).
+The cause of the difference appears to be symex-driven loading being more pessimistic about possible
+exceptions coming from callees, which in turn changes the shape of the CFG.
