SA0102 : False Positive (CSharp.CsParser : A syntax error has been discovered)

[Roman-Didenko]

The following code:

Func<object> x = () => null;
decimal t = x() as decimal? ?? 0;

incorrectly gives:
SA0102 : CSharp.CsParser : A syntax error has been discovered in file ....

Build 4.7.58.3

I have also discovered a false positive for this rule. This one regarding C#6 strings:

var from = "2015-01-01";
var to = "2016-01-01";
var token = $"{{ \"From\": \"{from}\", \"To\": \"{to}\" }}";

I get SA0102 : CSharp.CsParser : A syntax error has been discovered in file... for the below line

public static MySingletonInstance Instance => LazyInstance.Value;

How can I fix this?

I have the same false positive with this line of code:

dataEntryOutlineDiv.Attributes["class"] = "divHeightButton";

The false positive is not as big a problem as it is the fact that I get no style checking for the file at all. So it is in fact a failure of StyleCop
