Are you sure this fixes any segfault? example, the variant you have
below just changes a variable name:

-----
-static void free_opts(struct option *opts)
+static void free_opts(struct option *opts_local)
 {
-       if (opts != original_opts) {
-               free(opts);
+       if (opts_local != original_opts) {
+               free(opts_local);
                opts = original_opts;
                global_option_offset = 0;
        }
-------

You could respin the patch with comment "change bad smelling name of
a variable" - and that would be fine by me.

Please CC me on m_ipt or any of the other actions (as i have asked you
before).

cheers,
