Oh!  That's a regression.
Thank you for finding/reporting it!

Here's the fix I expect to use:

diff --git a/src/du.c b/src/du.c
index e4e36df..c1c0417 100644
--- a/src/du.c
+++ b/src/du.c
@@ -443,7 +443,9 @@ process_file (FTS *fts, FTSENT *ent)
               return false;
             }

-          if (fts->fts_options & FTS_XDEV && fts->fts_dev != sb->st_dev)
+          if (fts->fts_options & FTS_XDEV
+              && FTS_ROOTLEVEL < ent->fts_level
+              && fts->fts_dev != sb->st_dev)
             excluded = true;
         }
