Hi,

During a rebuild of all packages in sid, your package failed to build
on arm64 (I don't know if it also fails on amd64).

Relevant part (hopefully):
http://qa-logs.debian.net/2020/12/05/backward-cpp_1.5-2_unstable.log

A list of current common problems and possible solutions is available at
http://wiki.debian.org/qa.debian.org/FTBFS . You're welcome to contribute!

If you reassign this bug to another package, please marking it as 'affects'-ing
this package. See https://www.debian.org/Bugs/server-control#affects

If you fail to reproduce this, please provide a build log and diff it with me
so that we can identify if something relevant changed in the meantime.

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.

Hi,

This package only builds Arch:all binary packages. Unfortunately, I
don't think that we have a way to indicate that such binary packages
must be built on a specific architecture, and thus avoid a failure on
arm64.

In those cases, building those packages on amd64 works fine, so the bug
is limited to building arch:all packages on specific architectures.

I pondered downgrading the severity of those bugs, but in some cases,
it could indicate severe bugs in other packages, or packaging bugs such
as confusing arch:any and arch:all.

However, I don't object to someone else downgrading them.

Hi Lucas,

Thanks for al your QA work!

I'm doing so now.

Some of these are probably real bugs somewhere that should be fixed, but the
bugs doesn't need to be serious for that. These certainly aren't issues which
would merit delaying the release.

Note that if it turns out that some of these bugs are in fact caused by real
brokenness (other than not being able to build the arch: all packages on
arm64), the severity of those specific bugs can obviously be increased again
(with a note explaining what exactly is broken).

Cheers,

Ivo
