Using System.Diagnostics.Process.GetProcessesByName appears to cause an access
violation. 

Steps to reproduce: 

1. Compile the below code into assembly test.exe
2. Run "mono test.exe"

Code:

using System;
namespace test
{
        class MainClass
        {
                public static void Main(string[] args)
                {
                        System.Diagnostics.Process.GetProcessesByName("asdf");
                }
        }
}

Result:

$ mono test.exe
