嵌套ValueType并且写了binder情况下，CLR绑定，编译选项Optimize Code=true，热更域里某种写法会引起值解析不正确

[xushunwang]

外部值类型定义如下：

public struct TestStructA
{
    public long value;
}

public struct TestStructB
{
    public TestStructA m1;
    public TestStructA m2;
    public TestStructA m3;
    public TestStructA m4;
    public TestStructA m5;
    public TestStructA m6;
    public TestStructA m7;
    public TestStructA m8;
    public TestStructA m9;

    public static TestStructB GetOne(TestStructA a)
    {
        TestStructB ret = default;
        ret.m1 = new TestStructA { value = 1 };
        ret.m2 = new TestStructA { value = 2 };
        ret.m3 = new TestStructA { value = 3 };
        ret.m4 = new TestStructA { value = 4 };
        ret.m5 = new TestStructA { value = 5 };
        ret.m6 = new TestStructA { value = 6 };
        ret.m7 = new TestStructA { value = 7 };
        ret.m8 = new TestStructA { value = 8 };
        ret.m9 = new TestStructA { value = 9 };

        return ret;
    }

    public override string ToString()
    {
        return $"{m1.value}|{m2.value}|{ m3.value}|{ m4.value}|{ m5.value}|{ m6.value}|{ m7.value}|{ m8.value}|{ m9.value}";
    }
}

对应写了binder

热更域里这么使用：

namespace HotFix
{
    public static class HotFixLauncher
    {
        public static void Test()
        {
            MinCirclePath path = new MinCirclePath();

            path.Test();
        }

    }

    public class MinCirclePath
    {
        private TestStructB mAttr;

        public void Test()
        {
            mAttr = GetAttr();

            Debug.Log(mAttr);
        }

        private TestStructB GetAttr()
        {
            var a = new TestStructA() { value = 5 };

            //这样写不会错
            //var ret = TestStructB.GetOne(a);
            //return ret;

            //这样直接返回就会错
            return TestStructB.GetOne(a);
        }
    }
}

做了CLR方法绑定，并且热更代码编译一定要勾选上Optimize Code为true才会错。
指令上看不勾选只多了

1.6.7和2.0.2都有这个问题，unity2019.4
