            Bug ID: 118433
           Summary: Local scope deletion of a function is wrongly accepted
           Product: gcc
           Version: 14.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: fchelnokov at gmail dot com
  Target Milestone: ---

This program is accepted in GCC:

int main() {
    void bar() = delete;
}

with the warning
> warning: declaration of 'void bar()' has 'extern' and is initialized

but it shall be an error, since '= delete' is a function definition and must
occur in a standalone declaration.
