Zephir bug in incrementing array element

[cryptooman]

Hey. Seems found a bug in incrementing an array element in Zephir. Possible same presents also for the decrement.

array a = [0, 0, 1, 1];

let a[0] += 1; // 1

let a[1] = a[1] + 1; // 1

let a[2] += 1; // 1 <- expected 2

let a[3] = a[3] + 1; // 2

print_r(a);

Zephir 0.12.12, PHP 7.2.24-0ubuntu0.18.04.1

Please, check the same issue, but for the class static attributes.

namespace Test;
class TestBug
{
    private static _a;
    private static _b;

    public static function test() -> void
    {
        let self::_a = 0;
        let self::_b = 1;
        let self::_a += 1;
        let self::_b += 1;
        echo "test 1 _a: " . self::_a . " (epxect 1)\n";
        echo "test 1 _b: " . self::_b . " (epxect 2)\n"; // ?? 1

        let self::_a = 0;
        let self::_b = 1;
        let self::_a -= 1;
        let self::_b -= 1;
        echo "test 2 _a: " . self::_a . "  (epxect -1)\n"; // ?? 1
        echo "test 2 _b: " . self::_b . " (epxect 0)\n";

        let self::_a = 0;
        let self::_b = 1;
        let self::_a = self::_a + 1;
        let self::_b = self::_b + 1;
        echo "test 3 _a: " . self::_a . " (epxect 1)\n";
        echo "test 3 _b: " . self::_b . " (epxect 2)\n";

        let self::_a = 0;
        let self::_b = 1;
        let self::_a = self::_a - 1;
        let self::_b = self::_b - 1;
        echo "test 4 _a: " . self::_a . " (epxect -1)\n";
        echo "test 4 _b: " . self::_b . " (epxect 0)\n";

        int a = 0;
        int b = 1;
        let a += 1;
        let b += 1;
        echo "test 5 a: " . a . " (epxect 1)\n";
        echo "test 5 b: " . b . " (epxect 2)\n";

        let a = 0;
        let b = 1;
        let a -= 1;
        let b -= 1;
        echo "test 6 a: " . a . " (epxect -1)\n";
        echo "test 6 b: " . b . " (epxect 0)\n";

        let a = 0;
        let b = 1;
        let a = a + 1;
        let b = b + 1;
        echo "test 7 a: " . a . " (epxect 1)\n";
        echo "test 7 b: " . b . " (epxect 2)\n";

        let a = 0;
        let b = 1;
        let a = a - 1;
        let b = b - 1;
        echo "test 8 a: " . a . " (epxect -1)\n";
        echo "test 8 b: " . b . " (epxect 0)\n";
    }
}
