           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++

This is the simple code example:
https://godbolt.org/z/jKGavbx7o

Post it here and let me not forget about it. 
If someone can fix it, I will really appreciate.

If not, I will fix it if I have time (Currently busy with working on RVV
support).

#include <algorithm>
        std::pair<unsigned, bool> full_add(unsigned a, unsigned b)
        { return std::make_pair(a + b, a + b < a); }
