compiler error testcase

To Reproduce:
1. Create a new class
2. Create the follow methods in the order given:
3. Add an empty constructor
4. Add an empty event definition
5. Add an empty destructor
6. Compile

In the test case given, Mono gives compiler exceptions at the line where the
destructor is declared.

Exception caught by the compiler while compiling:
   Block that caused the problem begin at: TestCase.cs(27,18):
Mono.CSharp.InternalErrorException: parameter information mismatch
Internal compiler error at TestCase.cs(27,18):: exception caught while emitting
MethodBuilder [TestCase::Finalize]

Unhandled Exception: Mono.CSharp.InternalErrorException: parameter information
  at Mono.CSharp.ToplevelBlock.ResolveMeta (Mono.CSharp.EmitContext ec,
Mono.CSharp.Parameters ip) [0x00000] 
  at Mono.CSharp.EmitContext.ResolveTopBlock (Mono.CSharp.EmitContext
anonymous_method_host, Mono.CSharp.ToplevelBlock block, Mono.CSharp.Parameters
ip, IMethodData md, System.Boolean& unreachable) [0x00000] 

If you move the dtor above the event definition, then the errors do not occur.
