Brian,

	Sorry about the lack of information -- from reading the code, I just
assumed that the behavior I get was intentional.  I built bash-1.02 with
exactly one change (prior to commenting out the line I mentioned), and that
was just the MAINTAINER definition.  I'm running on a SUN 3/50 with OS 4.0.1.
(Note: I'm using gcc-1.35 with -traditional to compile bash.)

I have the following environment (using bash as my default shell):

xagsun% set
_=/usr/spool/mail/romine
OLDPWD=/usr/kvm
printman={
if [ $# -eq 1 ]  ; then
if [ -r $1 ]  ; then
cat $1 | rsh seq psditroff -man - 
else
filenam=`whereis -m $1` ; filenam=$filenam:$ ; if [ -r $filenam ]  ; then
cat $filenam | rsh seq psditroff -man - 
else
echo "function printman: file not found" 
fi

fi

else
echo "function usage: printman <name>" 
fi

}
print={
for v in $*; do if [ -r $v ]  ; then
case "$v" in 
  *.ps)
cat $v | rsh seq lpr -Plw1 ; shift 
  ;;
  *.l | *.man | *.[1-8])
cat $v | rsh seq psditroff -man - ; shift 
  ;;
  *)
cat $v | rsh seq enscript -G -fCourier-Bold8 ; shift 
  ;;
esac
else
echo "$v: No such file or directory" 
fi
; done
}
man={
if [ -r $1 ]  ; then
nroff -man $1 | less 
else
/usr/ucb/man $* 
fi

}
malias={
for v in $*; do grep $v $HOME/.mailrc ; done
}
look={
for v in $*; do /usr/bin/look -df $v /usr/sun1/local/src/ispell/web | awk -f /us
r/sun1/u0/romine/lib/ispell/expand.new.awk ; done

(Note: the artificially high value of SHLVL is due to exec-ing new versions,
but the behavior is reproducible in any case).

xagsun% type cd
cd is a shell builtin

xagsun% cd foobar
./foobar: No such file or directory
../foobar: No such file or directory
/usr/u0/romine/foobar: No such file or directory
/usr/foobar: No such file or directory
/usr/sun1/foobar: No such file or directory
/usr/sun2/foobar: No such file or directory
/usr/sun1/u0/foobar: No such file or directory
/u0/foobar: No such file or directory
/u1/foobar: No such file or directory
/u2/foobar: No such file or directory
/seq0/foobar: No such file or directory
/foobar: No such file or directory
foobar: No such file or directory
foobar: No such file or directory

As I mentioned, commenting out the `offending' line of code, as in the following
segment from builtin.c does the trick:

  else
    {
      if (chdir (newdir) < 0)
        {
/*
 *      commented out by romine to prevent a flurry of `file not found'
 *      messages when changing to a nonexistent directory, with CDPATH
 *      nonnull
 *        file_error (newdir);
 */
          return (0);
        }
      else
        {
          return (1);
        }
    }
}



Let me know if there is anything
further that I can do to help you.  And, by the way, I'm using bash as my
default shell, not because I think its buggy, but because it's very well-
and carefully-crafted.  Thanks for the work you put in.  It shows.

(P.S.  If it helps, with CDPATH unset, I get two copies of the message, i.e.

xagsun% unset CDPATH
xagsun% cd foobar
foobar: No such file or directory
foobar: No such file or directory
xagsun%
