--- Comment #8 from Jürgen Reuter <juergen.reuter at desy dot de> ---
What is the status of this problem? I checked with Darwin 22.2 and XCode 14.2,
and the problem still persists with the Git master, cf. below. Is there a
workaround for the moment? Will this be resolved before the release of gcc14?
