--- Comment #10 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
You only looked at the first error message and thought that.
I looked at:
/opt/compiler-explorer/gcc-trunk-20240921/include/c++/15.0.0/bits/locale_facets.h:2626:49:
error: expected unqualified-id before '(' token [-Wtemplate-body]
2626 | { return use_facet<ctype<_CharT> >(__loc).is(ctype_base::lower,
__c); }
To see where the problem would be.
