Bug#996278: open3d: autopkgtest needs update for new version of gcc-defaults: output on stderr

[Paul Gevers]

Source: open3d
Version: 0.9.0+ds-6
Severity: serious
Tags: sid bookworm
User: debian-ci at lists.debian.org
Usertags: needs-update
Control: affects -1 src:gcc-defaults

Dear maintainer(s),

With a recent upload of gcc-defaults the autopkgtest of open3d fails in
testing on arm64, armhf and ppc64el when that autopkgtest is run with
the binary packages of gcc-defaults from unstable. It passes when run
with only packages from testing. In tabular form:

                       pass            fail
gcc-defaults           from testing    1.194
open3d                 from testing    0.9.0+ds-6
all others             from testing    from testing

I copied some of the output at the bottom of this report. The failure is
due to output on stderr. Output to stderr is by default considered by
autopkgtest as a failure of the test. If you want to have test fail on
output to stderr, please fix the reason of the output. If you don't care
you can add the allow-stderr restriction to have autopkgtest ignore the
output.

Currently this regression is blocking the migration of gcc-defaults to
testing [1]. Of course, gcc-defaults shouldn't just break your
autopkgtest (or even worse, your package), but it seems to me that the
change in gcc-defaults was intended and your package needs to update to
the new situation.

If this is a real problem in your package (and not only in your
autopkgtest), the right binary package(s) from gcc-defaults should
really add a versioned Breaks on the unfixed version of (one of your)
package(s). Note: the Breaks is nice even if the issue is only in the
autopkgtest as it helps the migration software to figure out the right
versions to combine in the tests.
