Log4net bug when using ThreadContext

[Oren Eini]

The following code is failing, even though it looks like it can work:   MemoryAppender appender = new MemoryAppender(); ILog logger = LogManager.GetLogger("foo");   BasicConfigurator.Configure(appender);   using (log4net.ThreadContext.Stacks["1"].Push(null)) {     logger.Error("Should work"); }   Debug.Assert(appender.GetEvents().Length != 0);
