Preprocessed example that reproduces the error.
GCC 10.1.0 came with libstdc++ that has `<ranges>` implemented. Also clang 10
supports concepts. I wanted to use clang to compile a simple snippet that
relies on ranges, but clang encountered some errors that just don't happen with
gcc.
```
#include <ranges>
int main(void)
{
char c[3] = {'a', 'b', 'v'};
std::ranges::subrange sub(c);
}
```
The preprocessed file can be found here: <a href="https://godbolt.org/z/7hfbq5">https://godbolt.org/z/7hfbq5</a>
I've also made an attachment with the same preprocessed file compressed.</pre>
