Jump to case label crosses initialization of 'Foo foo'

From Cppsyntax

According to this, you have to use { } inside a case statement when declaring variables.

WRONG

  switch(typ) {
    case 1:
      MyClass* class = new MyClass();
      ...
    case 2:
  }

CORRECT

  switch(typ) {
    case 1: {
      MyClass* class = new MyClass();
      ...
    }
    case 2:
  }
