+Summary: String.Split incorrect behavior with RemoveEmptyEntries
+
+Description of Problem:
+String.Split returns the wrong number of substrings when using
+StringSplitOptions.RemoveEmptyEntries and specifying a maximum number of
+substrings to return.
+
+Example program to reproduce this bug:
+class TestProgram
+{
+ static void Main()
+ {
+ System.Console.WriteLine(string.Join(", ",
+ "a--b--c-d-e".Split(new char[]{'-'},4,
+ System.StringSplitOptions.RemoveEmptyEntries)));
+ }
+}
+
+Actual Results:
+a, b, -c-d-e
+(3 items returned from Split)
+
+Expected Results:
+a, b, c, d-e
+(4 items returned from Split)
+
+How often does this happen?
+Always.
+
+Additional Information:
+Microsoft .NET implements this correctly.
+
+I would consider this a "Critical" bug because it's an incorrect
+implementation of a core component, and will cause correctly-written
+applications to behave incorrectly.
