Segfault when a public function uses a private type alias

[anarthal]

namespace repro {

class S
{
    using type = int;

public:
    void f(type) {}
};

}  // namespace repro

int main() {}

Crashes with:

/usr/include/c++/14/bits/unique_ptr.h:447: typename std::add_lvalue_reference<_Tp>::type std::unique_ptr<_Tp, _Dp>::operator*() const [with _Tp = clang::mrdocs::TypeInfo; _Dp = std::default_delete<clang::mrdocs::TypeInfo>; typename std::add_lvalue_reference<_Tp>::type = clang::mrdocs::TypeInfo&]: Assertion 'get() != pointer()' failed.
PLEASE submit a bug report to https://github.com/cppalliance/mrdocs/issues/ and include the crash backtrace.
