[Bug 488115] Re: ruby garbage collector segfaults under certain conditions
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 [1].

Is there a non-GUI way of gaining access to the karmic-proposed distro?

The message sent by the way this bug was handed is: We know better than the Debian maintainers, and don't want to backport new versions even if they only contain important bug fixes. Sorry if it came across that way, it was certainly not meant to be the message. We just have been severely burned several times by being too liberal with changes to stable releases. All the changes in that Debian package were never tested (with feedback) on a karmic system, so we better apply changes individually. If there are more fixes to apply in stables (like the crash you mentioned), which have a confirmed patch and no unrelated changes, these are fine for SRU as well, of course. -- ruby garbage collector segfaults under certain conditions https://bugs.launchpad.net/bugs/488115 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Lucas, would it be possible to only backport the particular fix for this crash?

[Bug 488115] Re: ruby garbage collector segfaults under certain conditions
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 in Ubuntu. The debdiff between the current version in karmic and my SRU is attached. Note that the debdiff between the current version in Debian and the SRU is much smaller, obviously. I've uploaded the proposed SRU to karmic-proposed. ** Attachment added: ruby1.8_1.8.7.174-1ubuntu0.1.debdiff http://launchpadlibrarian.net/36229888/ruby1.8_1.8.7.174-1ubuntu0.1.debdiff -- ruby garbage collector segfaults under certain conditions https://bugs.launchpad.net/bugs/488115 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
