Title:
ruby garbage collector segfaults under certain conditions
To manage notifications
Ronen, the bug that Lucas mentioned in #19 is not fixed in Ubuntu. The
original bug listed in the bug description was fixed in
ruby1.8=1.8.7.174-1ubuntu1 which is in karmic-updates now.
So you don't need to add karmic-proposed. If you did, there are
directions for configuring it using the GUI at
Thanks for clarifying, Bryan. The GC bug-fix works.

Is there a non-GUI way of gaining access to the karmic-proposed distro? I
edited the sources.list, did an apt-get update and did this:
apt-get install --reinstall ruby1.8=1.8.7.174-1ubuntu1
apt-get install --reinstall libruby1.8=1.8.7.174-1ubuntu1
It appears to download and reinstall something,

I can confirm that updating to the proposed versions of ruby and libruby
fix the segfault test cases, and I have not observed any regressions in
my testing.

Installed ruby1.8 and libruby1.8 version 1.8.7.174-1ubuntu1 from karmic-
proposed.
Ran both tests successfully with experiencing a segfault
Was that meant to say without, or is there yet another one?
Thanks! Martin

My mistake.
*without* a segfault.
Works as expected.

Lucas, would it be possible to only backport the particular fix for this
crash? There seem to be a lot of other changes, which make the SRU very
difficult to review, and open possibilities for regressions. Thanks!
** Also affects: ruby1.8 (Ubuntu Karmic)
Importance: Undecided
Status:
It would be possible, but there's not much value to it. The other
bugfixes also fix relatively severe bugs. Also, 1.8.7.174-2 was uploaded
to Debian mid-august, so it received a lot of testing.

Hi,
I prepared a SRU to fix this bug and #484756 in karmic. The SRU consists
in backporting all the Debian changes, including Bryan's patch, to the
karmic package (there was no new upstream version in the meantime). So,
as a bonus, it also fixes several bugs that were reported in Debian, but
not
Ah, I would also need a sponsor, since ruby1.8 is in main, and I'm not
allowed to upload to main (my upload was rejected).

ruby garbage collector segfaults under certain conditions
I can reproduce this bug using both the upstream test, and the chef
package is affected by it:
$ sudo chef-client
[Wed, 25 Nov 2009 10:43:36 +] INFO: Starting Chef Run
/usr/lib/ruby/1.8/systemu.rb:54: [BUG] Segmentation fault
ruby 1.8.7 (2009-06-12 patchlevel 174) [x86_64-linux]
Aborted
Attached patch builds against ruby1.8=1.8.7.174-1 (karmic) and
ruby1.8=1.8.7.174-2 (squeeze) and fixes both the Time test, and resolves
the segfault running the chef package.
Patch filed upstream with debian as well.

Bryan, would you mind preparing:
- a debdiff against the current karmic version that:
+ backports the changes from the current Sid package
+ adds this patch
- a debdiff against the current sid package, targetted for Debian, that adds
this patch ?
That way, I could upload the first one to
