[Mono-dev] Issues with Thread.CurrentThread on 4.2

[Martin Potter]

We have some code which works on Microsoft's runtime and used to work on Mono 3.12, but now fails on Mono 4.2. Simplified code to reproduce the issue is as follows:

public class WorkStateThread
{
public void Start()
{
m_thread = new Thread(ThreadProc);
m_thread.Start(Thread.CurrentThread);
m_thread.Join();
}

private void ThreadProc (object objData)
{
if (m_thread != Thread.CurrentThread)
throw new InvalidOperationException ("m_thread != Thread.CurrentThread");
}

Thread m_thread;
}

class MainClass
{
public static void Main (string[] args)
{
WorkStateThread ws = new WorkStateThread ();
ws.Start ();
Console.WriteLine ("Done");
}
}

[TestFixture]
public class Test
{
[Test]
public void TestCase ()
{
WorkStateThread ws = new WorkStateThread ();
ws.Start ();
}
}

This code runs as expected when run from the command line, but if run as part of a unit test using NUnit, the InvalidOperationException is thrown.
