            Bug ID: 115134
           Summary: Possible typo in  _Grapheme_cluster_iterator iterator
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pilarlatiesa at gmail dot com
  Target Milestone: ---

I believe there's a missing dereference here:
https://github.com/gcc-mirror/gcc/blob/bc6e336cb7c85094ddc77757be97c3d8588f35ca/libstdc%2B%2B-v3/include/bits/unicode.h#L805

i.e.:

        constexpr _Iterator
        operator++(int)
        {
          auto __tmp = *this;
          ++*this; // here
          return __tmp;
        }
