Undefined index access succeeded.

Version: v0.3.3: Atlantis
Description: The array arr is not initialized, yet when accessing arr[1], the program executes successfully. However, if this code is run in solc+EVM, it will throw an error.

contract c {
    bytes arr;
    function f() public { bytes1 a = arr[1];}
}

Reproduction: I set up a Solang compilation and execution environment to test the program.

solang/target/debug/vmRunNoPara test.sol c f

The program executes normally.
