            Bug ID: 102820
           Summary: Failure to compile void{}
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gabravier at gmail dot com
  Target Milestone: ---

void f()
{
    void{};
}

This has been considered valid since
http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#2351 was accepted
as a DR in 2018, but GCC fails to compile it, with this error:

<source>: In function 'void f()':
<source>:3:10: error: compound literal of non-object type 'void'
    3 |     void{};
