I can certainly provide an example.

Code:
int main(int argc, char** argv) {
  int x = 5;
  int y = 2;
  return (x * y);
}

Old -ast-dump:
(TranslationUnitDecl 0x5341640 <<invalid sloc>>
  (TypedefDecl 0x5341b80 <<invalid sloc>> __int128_t '__int128')
  (TypedefDecl 0x5341be0 <<invalid sloc>> __uint128_t 'unsigned __int128')
  (TypedefDecl 0x5341fa0 <<invalid sloc>> __builtin_va_list '__va_list_tag
[1]')
  (FunctionDecl 0x53421a0 <simple.cc:1:1, line:5:1> main 'int (int, char
**)'
    (ParmVarDecl 0x5342000 <line:1:10, col:14> argc 'int')
    (ParmVarDecl 0x53420d0 <col:20, col:27> argv 'char **')
    (CompoundStmt 0x536e8a0 <col:33, line:5:1>
      (DeclStmt 0x53422d8 <line:2:3, col:12>
        (VarDecl 0x5342260 <col:3, col:11> x 'int'
          (IntegerLiteral 0x53422b8 <col:11> 'int' 5)))
      (DeclStmt 0x536e7a0 <line:3:3, col:12>
        (VarDecl 0x5342300 <col:3, col:11> y 'int'
          (IntegerLiteral 0x536e780 <col:11> 'int' 2)))
      (ReturnStmt 0x536e880 <line:4:3, col:16>
        (ParenExpr 0x536e860 <col:10, col:16> 'int'
          (BinaryOperator 0x536e838 <col:11, col:15> 'int' '*'
            (ImplicitCastExpr 0x536e808 <col:11> 'int' <LValueToRValue>
              (DeclRefExpr 0x536e7b8 <col:11> 'int' lvalue Var 0x5342260
'x' 'int'))
            (ImplicitCastExpr 0x536e820 <col:15> 'int' <LValueToRValue>
              (DeclRefExpr 0x536e7e0 <col:15> 'int' lvalue Var 0x5342300
'y' 'int'))))))))
