           Summary: System.Reflection.TargetInvocationException when
                    calling MethodInfo.invoke
    Classification: Mono
           Product: Mono: Runtime
           Version: 2.4.x
          Platform: x86
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: misc
        AssignedTo: mono-bugs at lists.ximian.com

The bug appears when trying to use the C# application OMeta#
(https://ometasharp.svn.codeplex.com/svn/).

When trying to translate a grammar using
OMetaSharp.Grammars.ParseGrammarThenOptimizeThenTranslate a call to
System.Reflection.MonoMethod.Invoke throws a
System.Reflection.TargetInvocationException.

Reproducible: Always

Steps to Reproduce:
In a shell do:
tar -xzf ometacrash.tar.gz
/loadCompileRun.sh

This will
- load the OMeta sources from https://ometasharp.svn.codeplex.com/svn/trunk
- compile the required assemblies OMetaSharp.dll and OMetaSharp.OMetaCS.dll
- compile and run the test application
Actual Results:  
Unhandled Exception: System.Reflection.TargetInvocationException: Exception has
been thrown by the target of an invocation. --->
System.InvalidProgramException: Invalid IL code in (wrapper runtime-invoke)
