The following test method doesn't return (waited for up to 5 minutes).

        [TestMethod()]
        public void Unpack_UsingBracketRepeaters_Matches()
        {
            string description = "[10]b";
            byte[] buffer = new byte[] {0, 0, 0, 0, 0, 0, 0, 0, 0, 0};
            byte[] expected = buffer;
            int startIndex = 0;

            IList actual = DataConverter.Unpack(description, buffer,
startIndex);

            CollectionAssert.AreEqual(expected,actual);
        }

Reproducible: Always

Steps to Reproduce:
        [TestMethod()]
        public void Unpack_UsingBracketRepeaters_Matches()
        {
            string description = "[10]b";
            byte[] buffer = new byte[] {0, 0, 0, 0, 0, 0, 0, 0, 0, 0};
            byte[] expected = buffer;
            int startIndex = 0;

            IList actual = DataConverter.Unpack(description, buffer,
startIndex);

            CollectionAssert.AreEqual(expected,actual);
        }
Actual Results:  
Never returns from the Unpack method.

Expected Results:  
A passed test.
