Comment(by askalski):

 In the generated C code, the director is freed twice:

 {{{
 static void
 VGC_Fini(struct cli *cli)
 {

         VRT_fini_dir(cli, VGCDIR(_default));  // once...
         VRT_fini_dir(cli, VGCDIR(default_1));
         VRT_fini_dir(cli, VGCDIR(default_2));
         VRT_fini_dir(cli, VGCDIR(default_3));
         VRT_fini_dir(cli, VGCDIR(default_4));
         VRT_fini_dir(cli, VGCDIR(_default));  // ...and again
         VRT_re_fini(VGC_re_0);
 }
 }}}
