Dear maintainer(s),

With a recent upload of gcc-defaults the autopkgtest of faiss fails in testing 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    1.233
faiss                  from testing    1.13.2-1
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 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.
