### Description NonBacktracking seems to have an issue with repeaters processed under IgnoreCase and their impact on lazy loops. ### Reproduction Steps ```C# using System.Text.RegularExpressions; string pattern = ".*?\\da{2}"; string input = "This1Aa should 2Aa match"; Console.WriteLine($"Interpreter : {new Regex(pattern, RegexOptions.IgnoreCase).Match(input)}"); Console.WriteLine($"Compiled : {new Regex(pattern, RegexOptions.IgnoreCase | RegexOptions.Compiled).Match(input)}"); Console.WriteLine($"NonBacktracking: {new Regex(pattern, RegexOptions.IgnoreCase | RegexOptions.NonBacktracking).Match(input)}"); ``` ### Expected behavior ``` Interpreter : This1Aa Compiled : This1Aa NonBacktracking: This1Aa ``` ### Actual behavior ``` Interpreter : This1Aa Compiled : This1Aa NonBacktracking: This1Aa should 2Aa ``` cc: @olsaarik, @veanes
