 Short C# program using System.Reflection.Emit to reproduce the problem case

+Attached C# program reproduces the problem: it attempts to emit an 
+exception block without any catch blocks in it. On Mono this produces 
+the assertion failure reported above.
+
+On .NET 1.1 this throws an exception:
+Unhandled Exception: System.InvalidOperationException: Incorrect code 
+generation for exception block.
+   at System.Reflection.Emit.ILGenerator.EndExceptionBlock()
+   at ReflectionCrasher.Main()
+
+MSDN docs for ILGenerator.EndExceptionBlock indicate it should throw 
+this exception if "the end exception block occurs in an unexpected 
+place in the code stream":
+http://msdn.microsoft.com/library/default.asp?url=/library/en-us/
+cpref/html/frlrfSystemReflectionEmitILGeneratorMethodsTopic.asp
+
+An exception can be caught by a compiler and an internal error 
+reported, but the assertion just kills the runtime immediately.
