Public bug reported:
KSH uses .paths file in any directory in $PATH to define certain
variables. If, however, .paths is a directory instead of a file, ksh
fails immediately after invocation:
field@abipd:~$ echo $PATH
/home/field:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
field@abipd:~$ ksh
$ exit
field@abipd:~$ mkdir /home/field/.paths
field@abipd:~$ ksh
$ Segmentation fault (core dumped)
field@abipd:~$ rm -rf /home/field/.paths
field@abipd:~$ ksh
$ exit
field@abipd:~$ ksh --version
