Does it fail on the 14 branch as well?  If so the target milestone should be
14.2, otherwise the summary should be [15 Regression]

--- Comment #2 from Rainer Orth <ro at gcc dot gnu.org> ---
It started to regress on the gcc-14 branch indeed.  However, for simple
testsuite
failures, I often don't care about backports, provided the issue is fixed on
trunk.
