Forgot the example itself:

ArrayRef(std::initializer_list);
};

enum { OPT_u };
struct Linker {

void Linker::ConstructJob(const ArgList ) const {
Args.AddAllArgs({OPT_u});
}

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108071 --- Comment #6 from Jonathan Wakely --- The ConstCharArrayDetector is getting instantiated with const char* const instead of const char[1], so the partial specialization doesn't match.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108071 --- Comment #2 from Manuel Lauss --- (In reply to Richard Biener from comment #1) I get the same errors, but the whole file can be compiled without errors with gcc-12 (it needs to be preprocessed with gcc-12 as well), and with a gcc-13 checkout from 9 days ago. So in the last 9 days, something was introduced which caused these errors to appear.

and loads of warnings before/after. That's with no options - what options do
you use and what's your error?
