Re: [Mono-list] exceptions are not thrown from ThreadPool'ed thread objects?

[Mariano Alarcon]

I see the same results (exception not thrown) in my gentoo with mono 
1.0. But when I take the mcs binary and run it on my winxp with ms.net 
1.1 the exception is caught by the main thread. I don't know what the 
correct behavior should be, but there is certainly something different 
between the two implementations.

how about mono? can you see it not working when run under mono? including
1.1.1? then we need to bug this. would be nice if someone on monodev can
comment on this. is this an unsupported scenario?

It works as expected with ms.net without having to uncomment anything.

has anyone noticed this problem? that is if you have a ThreadPool'ed thread
object created, any exception thrown inside of that thread will not be
rethrown up at all. I ran into this accidentally while developing some
performance code..
here's an example, could someone please try this with .net compiler/runtime?
if you just compile and run it, the exception in _ThreadProc does not get
thrown.
now, if you uncomment regular thread definition below "ThreadPool" - you
will get "exception 2" get thrown.
any ideas? is this expected? I hope not...
using System;
using System.Threading;
public class main {
      static void Main() {
              // this will not throw exception 1 (seems to be a bug?)
              ThreadPool.UnsafeQueueUserWorkItem(new
                      WaitCallback(_ThreadProc), null);
              // uncomment this to thrown exception 2 (as expected)
              // new Thread(new ThreadStart(_ThreadProc2)).Start();
              Thread.Sleep(90000);
      }
      private static void _ThreadProc(Object state) {
              throw new Exception("exception 1");
      }
      private static void _ThreadProc2() {
              throw new Exception("exception 2");
      }
}
