Diagnostic Output - MemoryDiagnoser: InvalidOperationException: Sequence contains no elements

[dario-l]

Just make my first benchmark. Unfortunatelly at the end of execution in section of Diagnostic Output - MemoryDiagnoser I've got an exception and don't know what is causing it.

    public class Program
    {
        public static void Main(string[] args) => BenchmarkSwitcher
            .FromAssembly(typeof(Program).Assembly)
            .Run(args);
    }

    [RankColumn]
    [Orderer(SummaryOrderPolicy.FastestToSlowest)]
    [MemoryDiagnoser]
    public class TrimBenchmark
    {
        private const string value = "test56 320895y23r203 2=30592 35023 5789";
        private const string suffix = "...";
        private const byte maxLength = 10;

        [Benchmark]
        public string TrimOld() => value.TrimOld(maxLength, suffix);

        [Benchmark]
        public string TrimSpan() => value.Trim(maxLength, suffix);
    }

Hi @dario-l

Is there any chance that your benchmark is throwing? If so, I think I've already solved this problem in #1903, but a new version containing the fix has not been yet published to nuget.org.

Could you please try our preview package from https://benchmarkdotnet.org/articles/guides/nuget.html#nightly and see if it helps?
