            Bug ID: 82640
           Summary: gcc doesn't show errors on anonymous local variables
           Product: gcc
           Version: 7.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vanyacpp at gmail dot com
  Target Milestone: ---

GCC compiles the following code:

int main()
{
    int (*);
    int (&)[-1];
    auto const (&)[3];
}

I believe the code is incorrect as the local variables are unnamed.
