--- Comment #7 from Sergei Trofimovich <slyfox at gcc dot gnu.org> ---
Got a build failure of clang-14 on this week's gcc. Minimal example:
This week's gcc-13 fails:
$ result-bad/bin/g++ -c bug.cc.cc
bug.cc.cc: In member function 'void Linker::ConstructJob(const ArgList&)
const':
bug.cc.cc:19:18: error: call of overloaded 'OptSpecifier(const<unnamed enum>)'
is ambiguous
19 | Args.AddAllArgs({OPT_u});
| ~~~~~~~~~~~~~~~^~~~~~~~~
bug.cc.cc:9:3: note: candidate: 'OptSpecifier::OptSpecifier(unsigned int)'
9 | OptSpecifier(unsigned);
| ^~~~~~~~~~~~
bug.cc.cc:8:12: note: candidate: 'OptSpecifier::OptSpecifier(bool)'

OptSpecifier&)'
7 | struct OptSpecifier {

bug.cc.cc:7:8: note: candidate: 'constexpr

Lat week's gcc-13 is ok:
$ result-good/bin/g++ -c bug.cc.cc
Version:
$ result-bad/bin/g++ -v
Using built-in specs.
COLLECT_GCC=/<<NIX>>/gcc-13.0.0/bin/g++
