      The following bug which I reported in version 1.02 does not seem to have
      gone away in 1.03.

         If I execute a shell script for which I have execute permission, but
         which does not start with #!, bash runs it itself (via a recursive
         call on main() !!).  This is fine, except that if the parent bash is a
         login shell, so is the forked child, and it runs .profile.
         [ ... ]

   Are you sure?  I am sure that this is not the case.

Unless I'm doing something very wrong, it is still the case.

I removed my .bash_profile and my .bashrc.
.profile contains only the line
  echo "running .profile"
and /bin/true is
  exit 0

Then I get
bash$ bash-1.03 -login
running .profile
bash$ type true
true is /bin/true
bash$ true
running .profile
logout

If I change .profile to
  echo "running .profile, SHLVL=" $SHLVL
  true

Then I get
bash$ bash-1.03 -login
running .profile, SHLVL= 2
bash$ type true
true is hashed (/bin/true)
bash$ true
running .profile, SHLVL= 3
running .profile, SHLVL= 4
running .profile, SHLVL= 5
.. etc.

I do not know where `logout' comes from in the first case nor why the
profile does not run recursively as soon as I type bash-1.03 -login in
the second case.

bash-1.03 is GCC compiled on an HP300 running More/BSD, and I can
reproduce the problem in a similar way in 1.02 on a Sun3/80 running
SunOS4.
