            Bug ID: 101818
           Summary: Error message for the wrong name in designated
                    initializers could be improved
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hewillk at gmail dot com
  Target Milestone: ---

Consider: https://godbolt.org/z/8xrocoTcG

struct Op { int a, b; };
Op op{.a = 0,
      .x = 0,


      .b = 0};


Clang rejects with:
<source>:3:8: error: field designator 'x' does not refer to any field in type
'Op'
      .x = 0,
       ^
However, GCC rejects with:
<source>:6:13: error: 'Op' has no non-static data member named 'x'
    6 |       .b = 0};
      |             ^


It would be less confusing and more user-friendly if the cursor can actually
point to the x.

This is a dup of bug 95085.

I don't think this is a dup of PR 95085. In 95085, Barry described the error
message for this case as "gcc's diagnostic is absolutely excellent", but it is
obviously misleading.

Confirming for the missing location in the caret diagnostic.

Almost a dup of another bug from Barry though: PR 90475
