This seems like a problem in solidity. PrintUint print number ascending from 1 to 4, instead of 1, 1, 2, 2

dynamicArrays.sol

pragma solidity ^0.4.0;
contract test {
    event PrintUint(uint256 _value);
    
    function testA() {
        uint256 x = 5;
        uint256[] A;
        uint256[] B;
        for(uint256 i = 0; i < 2; i++) {
            A.push(i);
            PrintUint(A.length);
            B.push(0);
            PrintUint(A.length);
        }
    }
}

If somebody found this: here is the solution: https://gitter.im/ethereum/solidity?at=59484e8c6462d8493c2c7a00
Declare variable in memory, local variable in storage is messy.
