Dear maintainer(s),

With a recent upload of luajit the autopkgtest of knot-resolver fails in
testing when that autopkgtest is run with the binary packages of luajit
from unstable. It passes when run with only packages from testing. In
tabular form:

                        pass            fail
luajit                 from testing    2.1.0~beta3+git20210112+dfsg-2
knot-resolver          from testing    5.4.4-1
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of luajit to testing
[1]. Due to the nature of this issue, I filed this bug report against
both packages. Can you please investigate the situation and reassign the
bug to the right package?

Control: reassign -1 src:luajit 2.1.0~beta3+git20210112+dfsg-2
Control: retitle -1 luajit SEGFAULTs on ppc64el

knot-resolver has been removed from testing due to this bug report, but
can't migrate back because a newer version fails to build on ppc64el.
Also other reverse dependencies of luajit show SEGFAULT in their
autopkgtest on ppc64el, so this seems a problem in luajit. Unfortunately
(Release Team member opinion) luajit is a key package so can't be
trivially removed. Can you (maintainer and ppc64el porters) please have
a look?

Paul

Hi,

If this issue is difficult to fix, how about removing luajit from
ppc64el? I noticed that the only reverse (build) dependent key package
of luajit (src:efl) already switched to plain lua on ppc64el (probably
because of this issue).

Paul

Hi Paul,
sorry for the late reply.
As I said on debian-devel, I've not enough expertise nor hope on that
topic.
Switching to lua is the way I went a few times, instead on relying on
luajit.

Hi,

Not convinced I'm totally right there's no key packages in the list
above, but let's go this route unless somebody puts up the effort to
*maintain* the ppc64el parts.

The list above only includes direct depends of libluajit-5.1, I still
need to figure out which packages build depend on libluajit-5.1-dev on
ppc64el and successfully build there.

For the bug which remains assigned to luajit, I want it to ensure that
in the future we don't accidentally have a successful build on ppc64el
with broken content, so please either drop ppc64el from the list of
architectures for which it builds or, better, add a build-time test that
fails while luajit segfaults.

Paul

We believe that the bug you reported is fixed in the latest version of
ettercap, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1011298@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
