            Bug ID: 111164
           Summary: The error message for a literal operator accepting an
                    argument of the wrong type is confusing
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hewillk at gmail dot com
  Target Milestone: ---

template<char...>
int operator ""_x ();

int x = "abc"_x;

The error message given by GCC includes:

<source>:4:9: note:   expected a constant of type 'char', got 'char'

This is paradoxical.
