            Bug ID: 87148
           Summary: backward compatibility issue  to take char [] as
                    incomplete type
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: will.xzm at gmail dot com
  Target Milestone: ---

struct Tst{
   char t[];
};
new Tst();

It will fail when compiled by gcc (7.3 or 8.2)
error: value-initialization of incomplete type [1mchar []

I have to correct to "char t[0]"; 

but with gcc 4.8.2 , it works fine. 

Is it by design ?? 
Is there  alternative way to make last version to  compile successfully without
modify code ??
