Exception when testing non-existent property of Uint32Array and bug with throw inside switch()

ok, as promised some sample code to reproduce the second problem when throwing inside a switch statement.

without switch(), everything behaves as expected:

process.on('uncaughtException',(err)=>{
  console.log('!!!UNCAUGHTEXCEPTION!!!',err);
});
/*
expect output === achieved output:
  -D0-
  -D1-
  CATCHED ... "simulate crash"
  -D8-
  -D9-
*/
function test( crit){
  try{
    const arr= new Uint32Array([1,2,3,4]);
    console.log('-D1-');
    if( crit) throw new Error('simulate crash');	// such as thrown by testing  Uint32Array.xyz
    console.log('-D2-');
  }
  catch(err){
    console.log('CATCHED',err);
  }
  console.log('-D8-');
}

console.log('-D0-');
test('crash');
console.log('-D9-');

adding the switch() brings up some fancy extras:

process.on('uncaughtException',(err)=>{
  console.log('!!!UNCAUGHTEXCEPTION!!!',err);
});
function test( crit){
  try{
    const arr= new Uint32Array([1,2,3,4]);
    console.log('-C1-');
    switch (crit) {
      case 'ok':  
        console.log('-C2-C3-');	
        break;

      default:  
        console.log('-C2-');
        if( crit) throw new Error('simulate crash');	// such as thrown by testing  Uint32Array.xyz
        console.log('-C3-');
        break;
    }		
    console.log('-C4-');
  }
  catch(err){
    console.log('CATCHED',err);
  }
  console.log('-C8-');
}

console.log('-C0-');
test('crash');
console.log('-C9-');

expected output (tested on chrome):

  -C0-
  -C1-
  -C2-
  CATCHED Error: simulate crash
  -C8-
  -C9-

achieved output:

  -C0-
  -C1-
  -C2-
  -C4-                                            * should not exist
  -C8-
  !!!UNCAUGHTEXCEPTION!!! ... "simulate crash"    * should be CATCHED
  -C9-
