On Mac OS X 10.6.3, with Mono 2.6.3 installed via the framework and CSDK
packages, I receive the following exception when I try to call
System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces():

Unhandled Exception: System.ArgumentException: length

System.Array destinationArray, Int32 destinationIndex, Int32 length) [0x00000]

I have attached a sample project that demonstrates this issue. 

Reproducible: Always

Steps to Reproduce:
1. Build and run code that invokes
System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces
Actual Results:  
A System.ArgumentException is thrown while
System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces is being
invoked.

Expected Results:  
The method should have returned an array of NetworkInterface objects available
on the system.
