[Dr. Werner Fink]

Hi,

just to be noted, tha patch:

-----------------------------------------------------------------
*** ../bash-4.2-patched/lib/glob/xmbsrtowcs.c   2010-05-30 18:36:27.000000000 
-0400
--- lib/glob/xmbsrtowcs.c       2011-03-14 14:22:11.000000000 -0400
***************
*** 174,180 ****
        wcslength = mbsnrtowcs(NULL, &tmp_p, nms, 0, &tmp_state);
  
        /* Conversion failed. */
!       if (wcslength == (size_t)-1)
        {
          free (wsbuf);
          *destp = NULL;
--- 174,180 ----
        wcslength = mbsnrtowcs(NULL, &tmp_p, nms, 0, &tmp_state);
  
        /* Conversion failed. */
!       if (wcslength == 0 || wcslength == (size_t)-1)
        {
          free (wsbuf);
          *destp = NULL;
-----------------------------------------------------------------

just breaks expansion like this one:

 > mkdir aaa
 > touch aaa/foo.a
 > touch aaa/foo.b
 > echo './aaa/foo'*
 ./aaa/foo*

in an arbitrary UTF-8 locale
