I can reproduce this in the `devel' branch.

The getopts loop is missing a `return' to break out of it. This should
fix it:

diff --git a/examples/loadables/realpath.c b/examples/loadables/realpath.c
index b19b87fb..7ea9a995 100644
--- a/examples/loadables/realpath.c
+++ b/examples/loadables/realpath.c
@@ -88,6 +88,7 @@ WORD_LIST     *list;
                        break;
                default:
                        builtin_usage();
+                       return (EX_USAGE);
                }
        }
