Dear Release Team,
[ Reason ]
The libmsgsl-dev package in stable is currently incompatible with std::variant
from GNU's libstdc++. To solve this issue, I propose a patch adding conditional
noexcept for the gsl::not_null template constructors.
[ Impact ]
My fix is necessary for backporting the newer versions of the telegram-desktop
package to the bookworm release. This is merely a bug fix so it should go to
stable-updates as per policy. https://backports.debian.org/Contribute/#index1h3
[ Tests ]
Manual. Published and viewed stories in Telegram Desktop.
[ Risks ]
Little. This header-only library has only one dependant, and for the changes to
be effective, the dependant package is need to be rebuilt.
[ Checklist ]
[x] *all* changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in stable
[x] the issue is verified as fixed in unstable
[ Changes ]
Only single new patch with the fix and autotests. For convenience, you can
review the difference in our GitLab.
