            Bug ID: 46416
           Summary: Clang accepts empty declaration in a class declaration
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org
          Reporter: haoxintu at gmail.com

This code bug.cc, Clang accepts it, while gcc, icc, or msvc rejects it.

$cat bug.cc
class A {
    int ;
    long ;
    char ;
};

For example in gcc,

$g++ -c bug.cc
bug.cc:2:5: error: declaration does not declare anything [-fpermissive]
     int ;
     ^
bug.cc:3:5: error: declaration does not declare anything [-fpermissive]
     long ;
     ^
bug.cc:4:5: error: declaration does not declare anything [-fpermissive]
     char ;

My clang version is

$clang++ --version
clang version 11.0.0 (https://github.com/llvm/llvm-project
