du -L -s not showing dirs containing symlinks to '.'

[Kevin Korb]

Hello,
I have found a problem with du that I believe is a bug...

As you can see from the total there are more dirs here being counted but
not listed in the summary:
# du -smLc */_boot.current
10      e/_boot.current
8       g/_boot.current
15      h/_boot.current
107     total

The files are all symlinks to directories and none are broken:
# file */_boot.current
a/_boot.current:         symbolic link to `_boot.2005-01-27.03-53-32'
b/_boot.current:         symbolic link to `_boot.2005-01-27.04-48-59'
c/_boot.current:         symbolic link to `_boot.2005-01-27.05-13-23'
d/_boot.current:         symbolic link to `_boot.2005-01-27.05-33-04'
e/_boot.current:         symbolic link to `_boot.2005-01-27.08-31-58'
f/_boot.current:         symbolic link to `_boot.2005-01-27.08-29-44'
g/_boot.current:         symbolic link to `_boot.2005-01-27.08-51-20'
h/_boot.current:         symbolic link to `_boot.2005-01-27.07-06-02'

This also happens when I du the directories directly bypassing the
symlinks:
# du -smLc a/_boot.2005-01-27.03-53-32 b/_boot.2005-01-27.04-48-59 
c/_boot.2005-01-27.05-13-23 d/_boot.2005-01-27.05-33-04 
e/_boot.2005-01-27.08-31-58 f/_boot.2005-01-27.08-29-44 
g/_boot.2005-01-27.08-51-20 h/_boot.2005-01-27.07-06-02
10      e/_boot.2005-01-27.08-31-58
8       g/_boot.2005-01-27.08-51-20
15      h/_boot.2005-01-27.07-06-02
107     total

However it works just fine without the -L:
# du -smc a/_boot.2005-01-27.03-53-32 b/_boot.2005-01-27.04-48-59 
c/_boot.2005-01-27.05-13-23 d/_boot.2005-01-27.05-33-04 
e/_boot.2005-01-27.08-31-58 f/_boot.2005-01-27.08-29-44 
g/_boot.2005-01-27.08-51-20 h/_boot.2005-01-27.07-06-02
16      a/_boot.2005-01-27.03-53-32
16      b/_boot.2005-01-27.04-48-59
16      c/_boot.2005-01-27.05-13-23
16      d/_boot.2005-01-27.05-33-04
8       e/_boot.2005-01-27.08-31-58
4       f/_boot.2005-01-27.08-29-44
8       g/_boot.2005-01-27.08-51-20
14      h/_boot.2005-01-27.07-06-02
95      total

The problem seems to be created by the fact that some of these
directores contain a symlink that points to the current directory (.):
# file */_boot.current/boot
a/_boot.current/boot: symbolic link to `.'
b/_boot.current/boot: symbolic link to `.'
c/_boot.current/boot: symbolic link to `.'
d/_boot.current/boot: symbolic link to `.'
f/_boot.current/boot:    symbolic link to `.'

When I remove that symlink the du works as expected:
# rm -v */_boot.current/boot
removed `a/_boot.current/boot'
removed `b/_boot.current/boot'
removed `c/_boot.current/boot'
removed `d/_boot.current/boot'
removed `f/_boot.current/boot'
# du -smLc */_boot.current
17      a/_boot.current
17      b/_boot.current
17      c/_boot.current
17      d/_boot.current
10      e/_boot.current
4       f/_boot.current
8       g/_boot.current
15      h/_boot.current

This is an AMD Opteron running Gentoo Linux.  The filesystem is

sure that the patches in Gentoo's portage were not the problem and my
clean compile worked exactly the same.
