There has been extensive discussion of this issue. Look at http://git.savannah.gnu.org/cgit/bash.git/log/?h=direxpand for a version of bash-4.2.24 with the changes described most recently in http://lists.gnu.org/archive/html/bug-bash/2011-12/msg00079.html Those changes address all of the bash-4.2 problems discussed and add a shell option to revert to the bash-4.1 behavior. That message has links to earlier discussions.
