Hi,

leptonlib currently fails to build from source on sparc64 due to unaligned access:

This has already been reported upstream [1].

Thanks,

Jonas, this alignment issue was reported on Sparc64. It was recently
addressed by upstream, but not yet brought into Debian. Mentioning in case
there is any interaction with the Rust bindings, which were also throwing
an error related to alignment.

Upstream has already released version 1.86.0. Time for a package update?

The debian/watch file doesn't seem to work either, FWIW. See this section [1]
in the Debian wiki on how to fix it for the new GitHub API.

Jeff, if you have time this fall, we should do a new Debian release for the
big Ubuntu distro in April 2026.

I somewhat screwed up the tag and release for 1.86.0, because I didn't use
a different 'prerelease' tag for the prerelease version.
So I'm putting out 1.87.0 in the next day or two, and will try to do it
correctly.

Looking at the 1.86.0 release on github, is there anything obviously wrong,
except perhaps that the autotools tarball was initially uploaded outside of
the assets (and perhaps someone copied it into the assets later?).
