/bin/dash Segmentation fault

Binary package hint: dash

# lsb_release -rd
Description: Ubuntu 8.04.1
Release: 8.04

# uname -a
Linux desk 2.6.24-19-generic #1 SMP Fri Jul 11 21:01:46 UTC 2008 x86_64 GNU/Linux

# ls -l /bin/dash
-rwxr-xr-x 1 root root 100856 Mar 12 12:52 /bin/dash

STEPS TO REPRODUCE
1. Build thunderbird from Mozilla source, instructions here:
http://developer.mozilla.org/en/docs/Comm-central_source_code_(Mercurial)

when ./configure runs it will crash /bin/sh (which is a symlink to dash).
Changing the symlink to bash instead makes ./configure run without error.

[L. David Baron (dbaron)]

As a result of the changes to configure.in in bug 442279, configure crashes on Ubuntu systems where /bin/sh is dash rather than bash, and when a config.cache is present from a previous run of configure. In other words, this crash is a result of the change:
http://hg.mozilla.org/mozilla-central/index.cgi/diff/9871082391f5/configure.in

I don't get why it crashes, but ok!

[Mats Palmgren (matspal)]

FWIW, I filed this to Ubuntu yesterday:
https://bugs.launchpad.net/ubuntu/+source/dash/+bug/251889

[Mats Palmgren (mats-palmgren)]

FYI, there are some more details (and a workaround!) here:
https://bugzilla.mozilla.org/show_bug.cgi?id=448020

[L. David Baron (dbaron)]

Ah, I didn't file because the obvious simplified testcase didn't exhibit the problem, and I wasn't in the mood to simplify configure down to a testcase (though it may be worth doing).

In any case, fixed:

Resolved upstream, Mats can you confirm this and close this bug? Thanks!

[Mats Palmgren (mats-palmgren)]

By "upstream" you mean Debian? or http://git.kernel.org/?p=utils/dash/dash.git;a=summary ?
or something else? What do want me to test exactly?

Landed in CVS.

[Phillip Susi (psusi)]

8.04 has reached end of life, and this was fixed long ago on the thunderbird side. If you have another way to reproduce the crash in dash on 12.04 or later, please update the description and change the status back to new.
