           Summary: SIGABRT error accessing
                    OperationContext.Current.OutgoingMessageHeaders
    Classification: Mono
           Product: MonoTouch
           Version: unspecified
          Platform: iPhone
        OS/Version: Apple iOS 4.3

Description of Problem: When accessing the OutgoingMessageHeaders property on
the current instance of OperationContext for the second time on an open channel
throws an ExecutionEngineException. This only happen on a devices, it doesn't
happen in the simulator.

Steps to reproduce the problem:
Using code similar to the following:

using (OperationContextScope scope = new
OperationContextScope(this.WCFServiceClient.InnerChannel))
{
   string ns = "http://something.com";
   OperationContext.Current.OutgoingMessageHeaders.Add(new
MessageHeader<string>("testValue"))
                                                                   
GetUntypedHeader("testName", ns));
   this.WCFServiceClient.SomeMethodAsync();
}

Run through the code twice, on the second run through an error will occur when
accessing the OutgoingMessageHeaders property.

Actual Results:
Unhandled Exception: System.ExecutionEngineException: SIGILL
* Assertion: should not be reached at ../../../../mono/mini/mini.c:2629

Debug info from gdb:


=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
=================================================================

Expected Results:
For the message header to add to the collection and the request to be sent.

How often does this happen? 
It happens everytime on the second web service call when running on an actual
device and not the simulator

Additional Information:
This is being compiled against Monotouch v3.99.13
