Problem with bash 3.xyz - Sep. 21, '06, 6:48:24 PM

After upgrade (with pkg_add) from bash 2.05.2.2 to 3.0.0.8 I can't start it as login shell from Windows' shortcut.

I just copied SFU's default shortcut to C shell and change its target from '%Windir%\posix.exe /u /c /bin/csh -l' to '%Windir%\posix.exe /u /c /usr/local/bin/bash -l'. This shortcut works fine for bash 2, but bash 3 starts and then exits immediately (terminal windows flashes for a second and then closed without any output). This behavior occurs in both SFU 3.5 on XP and SUA 6.0 on Vista RC1.

I still can run bash as login shell from csh. What goes wrong?

Check that it's listed in the /etc/shells file as
/usr/local/bin/bash

It is

% cd /etc
% cat ./shells
/bin/sh
/bin/ksh
/bin/csh
/bin/tcsh
/usr/local/bin/bash
%

You started it as "bash -l" then, yes?

If you start a CMD.EXE shell and then run "bash -l" does it give an error message?

Yes, when I start "bash -l" from "csh -l"'s prompt, it runs.

But when I start it from non-login csh or cmd.exe (or from shortcut), it simply doesn't run without any error messages.

In addition to XP and Vista, I tried to reproduce this problem in SUA 5.2 on W2k3 with domain environment -- exactly the same, bash 3 doesn't run as login shell, but bash 2 runs OK.

What command line were you using? It seems to work fine here from 4NT or CMD:

[C:\]posix /u /c /usr/local/bin/bash -l
Welcome to the Interix UNIX utilities.

DISPLAY=localhost:0.0
bash-3.00$ pwd
/dev/fs/C/SFU/home/eperea

I just remove all /Tools packages with pkg_delete and install everything onto clean-again SFU. Now bash 3 works as login shell. Perhaps, some old stuff in /etc/profile.lcl (that remains after bash 2 to 3 update with pkg_add? -- I don't know, because I replace profile.lcl with SFU's default one) prevents it from normal starting. %)

I experienced a similar problem just now.
I'm running Vista build 5728. Clean installed it and SFU today (for the first time).

Creating a shortcut which points to:
C:\Windows\posix.exe /u /c /usr/local/bin/bash -l
opens a window briefly, then dumps core.

As a workaround, I've just invoked bash from my .profile if $KSH_VERSION is set.

I'm thinking that for build 5728 of Vista this may be a problem with
the loading of the 3.5 shared libraries since static 3.5 binaries (such
as the installer) are running. There's always the chance that 5728 isn't
a good snapshot... I'll see if MS can tell me anything...

I figured I'd try compiling against the latest source (3.0.16)... http://ftp.gnu.org/pub/gnu/bash/

Configure line was:

./configure --prefix=/usr/local --enable-static-link --build=i586-pc-interix

... then a "gmake", which dies with:

gcc -c  -I. -I../.. -I../.. -I../../lib -I../../include -I.  -DHAVE_CONFIG_H -DS
HELL -DNO_MAIN_ENV_ARG -DBROKEN_DIRENT_D_INO  -D_ALL_SOURCE -D_ALL_SOURCE -I/usr

Which I assume are these bits of ./bash-3.0.16/lib/sh/strtol.c

Lines: 148-149

  cutoff = STRTOL_ULONG_MAX / (unsigned LONG int) base;
  cutlim = STRTOL_ULONG_MAX % (unsigned LONG int) base;

Lines: 223-224

              ? -((unsigned LONG int) (STRTOL_LONG_MIN + 1)) + 1
              : (unsigned LONG int) STRTOL_LONG_MAX))

Line: 234

      return negative ? STRTOL_LONG_MIN : STRTOL_LONG_MAX;

Just to clarify, bash does actually work fine for me when invoked from within ksh (with or without exec()ing over ksh).

Things are going more interesting.

Today I tried to install all my favorite bunch of /Tools packages on another machine with Vista RC1 (build 5600).

bash 3.0.0.8 dumps core on string 254 of default SUA's /etc/profile, when runs from shortcut/cmd/anything else as login shell.

# -------------
#
# Change directory to user's home directory.
# On UNIX, this would be done by the login(1) program, but since
# we don't always run login(1) (for example, from a shortcut) we emulate
# it here to be sure.
#
if [ "$HOME" != "" ]; then

cd "$HOME" # HERE bash does core

fi

# -------------
# now read in the system local profile
#
if [ -f /etc/profile.lcl ]; then
    . /etc/profile.lcl
fi

Just comment or remove this cd, or place it into /etc/profile.lcl, and then bash starts normally with -l switch!

Any ideas why?

Given the crash is a SEGV there is something getting stored or referenced with
a wrong value (I say "wrong" rather than "bad" since it might have been okay
sometime earlier). It certainly won't have anything to do with threads.

This is the second posting that has it happening with a "cd". So there might
be something in this code. I doubt it's the system API chdir() because other
apps that chdir() are functioning; it may be with backward compatible shared
libraries. I have sent e-mail to Microsoft asking if anything is known about
this.

I'm going to make a static 3.5 based bash to see what happens.

Well, that sucked. A static version (which has to have the 'enable' function,
ironically, disabled for a static build) still crashes the same way.
I get it kacking over when started as a login shell from a shortcut.
So... I'll try something else.

I've narrowed it down to the specific line in bash (a free() call).
I'm looking to see if there is a double free for this address or something like that.
But given I can see this same code work when started from within another shell
I think it has to be something else.
