[Mono-dev] Asynchronous socket segmentation fault

I'm running mono on Linux.
I have a UDP socket and when I call Close( ) before EndReceiveFrom( ) I 
get segmentation fault.
Running the same binary on .net only throws an exception.
Here's a backtrace:

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


in <0x4> (wrapper managed-to-native) 
in <0xffffff7b> (wrapper managed-to-native) 
in <0x4b> System.Net.Sockets.Socket:ReceiveFrom_nochecks 
in <0x5b> Worker:ReceiveFrom ()
in <0x13208> (wrapper delegate-invoke) 
System.MulticastDelegate:invoke_void ()
in <0x50f5c1ef> (wrapper runtime-invoke) 
System.Object:runtime_invoke_void (object,intptr,intptr,intptr)

Native stacktrace:

        /lib/tls/i686/cmov/libc.so.6(__clone+0x5e) [0xb7e72bde]

I'm very new to mono/c# (pretty much first day of coding), but I don't 
think this is expected behaviour, is it?
