Bash symlink not followed as expected.

Hey All,

Not sure if this is a bug but logging anyway just in case.

Rgds,

   * A description of the bug


Symlink path is not followed as expected.  For example:

bash-3.00# pwd
/ee/oce
bash-3.00# ls -l oracle
lrwxrwxrwx   1 oracle   oinstall       6 Oct 12 12:03 oracle -> ../oce
bash-3.00# cd oracle
bash-3.00# pwd
/ee/oce/oracle
bash-3.00# cd oracle
bash-3.00# pwd
/ee/oce/oracle/oracle
bash-3.00# cd oracle
bash-3.00# pwd
/ee/oce/oracle/oracle/oracle
bash-3.00# cd oracle
bash-3.00# pwd
/ee/oce/oracle/oracle/oracle/oracle
bash-3.00# sh
# pwd
/export/home/database/11g/oce
# cd /ee/oce
# ls -l oracle
lrwxrwxrwx   1 oracle   oinstall       6 Oct 12 12:03 oracle -> ../oce
# cd oracle
# pwd
/export/home/database/11g/oce
# cd oracle
# pwd
/export/home/database/11g/oce

   * A recipe for recreating the bug reliably

Make a directory and symlink back to a previous directory.

# cd /var/tmp
# mkdir tom
# cd tom
# ln -s ../tom link
# cd link
# pwd
/var/tmp/tom
# cd link
# pwd
/var/tmp/tom
# bash
bash-3.00# cd link
bash-3.00# cd link
bash-3.00# pwd
/var/tmp/tom/link/link

   * A fix for the bug if you have one!
