Known segfault in 1.1.19 (the current stable)

Could someone set the importance on this bug to High or higher? Thanks.

I was just bit by this too. http://forum.nginx.org/read.php?2,231787,231787#msg-231787

Marking fix released as this was fixed in upstream 1.2.0, and QUantal has a version newer than that.

Supplementary to Comment #3:

I will be cherrypicking the upstream patch and applying it to the Precise version, and will get this SRU'd.

This debdiff contains upstream code changes as part of a quilt patch. The patch was hand-made, as the upstream-generated diff would not apply, however the code changes are based in upstream.

The upstream code changes are located at http://trac.nginx.org/nginx/changeset/4601/nginx

Thomas, thanks for the debdiff, uploaded to precise-proposed where it will need to await SRU team approval (which may take a little while as the SRU/Release team are busy this week releasing 12.10)

Thanks for your help. I'm still trying to upload a browser? it says to
click on a new Browser and when I do the message still stays. I never get
away from the 3.6 one on my computer? How can I make the Browser download
stay and quit telling me to upgrade??

Oops, prior debdiff contained excess cruft (failed upstream diff file, which i later hand-made).

This one should contain a version that works. Resubscribed the sponsors team, because this'll need to replace the prior sponsored one.

Oops, failed attachment :/

This one should be the correct debdiff.

I'll resubscribe sponsors.

Uploaded, waiting for SRU review

I removed the From line from the patch since you were not the author.

Hello Eugene, or anyone else affected,

Accepted nginx into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/nginx/1.1.19-1ubuntu0.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Seems to work fine.

Thanks!

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.

This bug was fixed in the package nginx - 1.1.19-1ubuntu0.1

---------------
nginx (1.1.19-1ubuntu0.1) precise-proposed; urgency=low

  * Applies upstream bug fixes
    * Segfault with try_files when first URI is shorter than request URI
