Exceptions when working with VS2015 update 3

It threw exceptions when I was working in VS 2015 update 3. The stack trace was:

System.ArgumentOutOfRangeException: Microsoft.VisualStudio.Text.SnapshotSpan..ctor(ITextSnapshot snapshot, Span span)
CodeBlockEndTag.CBETagger.InvalidateSpan(Span invalidateSpan, Boolean clearCache)
CodeBlockEndTag.CBETagger.OnTextViewLayoutChanged(Object sender, TextViewLayoutChangedEventArgs e)
Microsoft.VisualStudio.Text.Utilities.GuardedOperations.RaiseEvent[TArgs](Object sender, EventHandler`1 eventHandlers, TArgs args)

It appeared that I'd fixed this issue. Please change the last two lines of the InvalidateSpan method in CBETagger.cs to the following lines. By checking the End of the span and the Length of the snapshot, the problem was gone.

if (invalidateSpan.End <= _TextView.TextBuffer.CurrentSnapshot.Length) {
    _changedEvent?.Invoke(this, new SnapshotSpanEventArgs(
        new SnapshotSpan(_TextView.TextBuffer.CurrentSnapshot, invalidateSpan)));
}
