I noticed that when I run a RegEx expression, it has inconsistent index positions of results when run in another machine. Am I missing something here...

Give this sql statement:

```cs
var sqlStatementRaw = $@"
--GO inline comment
CREATE PROC table1
AS
    SELECT 1;
GO

/*
GO in inline comment block
*/

CREATE PROC table2
AS
    SELECT 1;
GO

/* multiline comment block
GO
*/

CREATE PROC table3
AS
    SELECT 1;
";

```

And this pieace of code:

```cs
var resultList = new List<CommentAnalyzerResult>();

//all comments
//https://stackoverflow.com/questions/7690380/regular-expression-to-match-all-comments-in-a-t-sql-script/33947706#33947706
var regex = new Regex(@"/\*(?>(?:(?!\*/|/\*).)*)(?>(?:/\*(?>(?:(?!\*/|/\*).)*)\*/(?>(?:(?!\*/|/\*).)*))*).*?\*/|--.*?\r?[\n]", RegexOptions.Singleline | RegexOptions.CultureInvariant);

var match = regex.Match(sqlStatementRaw);
while (match.Success)
{
    var commentBlock = new CommentAnalyzerResult { Text = match.Value, Start = match.Index, End = match.Index + match.Length };
    resultList.Add(commentBlock);

    match = match.NextMatch();
}

```

Machine 1 results:

```
## results from my win10/x64 machine
Environment.OSVersion.Platform: Win32NT, Microsoft Windows NT 10.0.18362.0
Environment.NewLine.byteCount: 2

sqlStatementRaw.byteCount: 251

commentText.byteCount: 21
startPosition: 2, stopPosition: 23

commentText.byteCount: 34
startPosition: 75, stopPosition: 109

commentText.byteCount: 34
startPosition: 165, stopPosition: 199

```

Machine 2 results:

```
## results in AppVeyor Agents - Previous Visual Studio 2019 Image
Environment.OSVersion.Platform: Win32NT, Microsoft Windows NT 10.0.17763.0
Environment.NewLine.byteCount: 2

sqlStatementRaw.byteCount: 228

commentText.byteCount: 20
startPosition: 1, stopPosition: 21

commentText.byteCount: 32
startPosition: 68, stopPosition: 100

commentText.byteCount: 32
startPosition: 149, stopPosition: 181

```

**EDIT:**  

 - One machine is my Windows 10 dev machine and other is AppVeyor Build Image with VS2019  

- Using .NET Core 3.0, both machines are 64-bit. The tests are run via MsTest drivers.

**EDIT:**  

- Added more debug info: OS info, byte count
