NullReferenceException with no stack trace when hooking SetConsoleCtrlHandler

Using code to hook the console close event from this thread, I sometimes get a NullReferenceException with no stacktrace (most of the times I don't). It happens in both release and debug and 'break when an exception is thrown' doesn't help (it breaks, but the stack trace is still empty). I never get this exception when I exit my application normally (which is hitting enter and thus releasing a Console.ReadLine). The Application event log has 2 entries:


Application: MyApp.exe Framework Version: v4.0.30319 Description:
The process was terminated due to an unhandled exception. Exception
Info: System.NullReferenceException Stack:


And:

Google has revealed some bugs and issues with SetConsoleCtrlHandler, so I'm wondering if this is a lost battle.
