Bugzilla Bug 176432

'/bin/ls -x' dubly shows file list, depending on conditions.
I doubt that /bin/ls fails to sort directory entry, because following case
correctly works.
1. touch 1 a.cpio
2. ls -x


Reproducible: Sometimes

Steps to Reproduce:
1. touch a.cpio
2. touch 1
3. ls -x

Actual Results:  
$ ls -a
.  ..
$ touch a.cpio
$ ls -ax
.  ..  a.cpio
$ touch 1
$ ls -ax
.  ..  1  a.cpio
$ ls -x # THIS WORKS INCORRECTLY
a.cpioa.cpio
$ ls -l
total 0
-rw-r----- 1 ons users 0 Apr 29 14:47 1
-rw-r----- 1 ons users 0 Apr 29 14:47 a.cpio
$

Expected Results:  
$ ls -x
1  a.cpio

Hi.

I've tested this here and got some interesting results as well.

$ ls -a
.  ..
$ touch a.cpio
$ ls -ax
a.cpio..  a.cpio
$ touch 1
$ ls -ax
a.cpio..  1  a.cpio
$ ls -x
a.cpioa.cpio
