[Bug 2052929] Re: failed autopkgtests for evolver vs glibc 2.39 on amd64

[Łukasz Zemczak]

Hello Simon, or anyone else affected,

Accepted gcc-14 into noble-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/gcc-14/14.2.0-4ubuntu2~24.04 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 on 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 add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
noble to verification-done-noble. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-noble. In either case, without details of your testing we will
not be able to proceed.

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

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: gcc-14 (Ubuntu Noble)
       Status: New => Fix Committed

** Tags added: verification-needed verification-needed-noble
