Resolution Note:
The test case is invalid as there is an error in the script
```
WhereAt(ref v7, "v7");
if (v0 != 0x01234500) throw new Exception("v0 is incorrect");
if (v1 != 0x01234501) throw new Exception("v1 is incorrect");
if (v2 != 0x01234502) throw new Exception("v2 is incorrect");
if (v3 != 0x01234503) throw new Exception("v3 is incorrect");
if (v4 != 0x01234504) throw new Exception("v4 is incorrect");
if (v5 != 0x01234505) throw new Exception("v5 is incorrect");
if (v6 != 0x01234506) throw new Exception("v6 is incorrect");
-->> if (v6 != 0x01234507) throw new Exception("v7 is incorrect");
```
the comparison is done with the wrong variable, when the script code is updated to ` if (v7 != 0x01234507) throw new Exception("v7 is incorrect");` there is no error and `ref` feature in C# works as expected
