            Bug ID: 95873
           Summary: Duplicated warning message "'class' tag used in naming
                    'union a'"
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Keywords: diagnostic
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: haoxintu at gmail dot com
                CC: mpolacek at gcc dot gnu.org
  Target Milestone: ---

This code, bug.cc, GCC emits two duplicated warning messages.

$cat bug.cc
union a{};
auto var = new (typename :: a );

$g++ -c -fpermissive bug.cc
bug.cc:2:29: warning: 'class' tag used in naming 'union a' [-fpermissive]
    2 | auto var = new (typename :: a );
      |                             ^
bug.cc:1:7: note: 'union a' was previously declared here
    1 | union a{};
      |       ^
bug.cc:2:29: warning: 'class' tag used in naming 'union a' [-fpermissive]
    2 | auto var = new (typename :: a );
      |                             ^
bug.cc:1:7: note: 'union a' was previously declared here
    1 | union a{};
      |       ^

All GCC-6 to GCC-trunk versions have this issue.

The warning is invalid in this case anyways so even though there is a
duplicated warning it only happens with valid code which should not warn at
all.
