     Hello,

     I have ran into similar issue. The following patch fixes for me:

diff --git a/frontend/scanimage.c b/frontend/scanimage.c
index ce958df..49030a3 100644
--- a/frontend/scanimage.c
+++ b/frontend/scanimage.c
@@ -2091,7 +2091,7 @@ Parameters are separated by a blank from 
single-character options (e.g.\n\

        /* re-run argument processing with backend-specific options included
         * this time, enable error printing and arg permutation */
-      optind = 0;
+      /* optind = 0; */
        opterr = 1;
        while ((ch = getopt_long (argc, argv, full_optstring, all_options,
                                 &index)) != EOF)

     Since the current has been correct for years,  maybe there is a 
regression in glibc ?
