Summary:                    Using generic method inside try-block fails to
compile
Description: 
The following code fails to compile (using nemerle and mono svn head):

public class A['a] {
    public Nothing():void {}

    public Fun():void {
        try {
            Nothing();
        } finally {
        }
    }
}



** ERROR **: file reflection.c: line 835 (method_encode_clauses):
assertion failed: (ex_info->handlers)
aborting...

I don't know whether this is a bug in nemerle or in mono, however the
following C#-code compiles cleanly:

public class A<T> {
  public void Nothing() {}

  public void Fun() {
    try {
      Nothing();
    } finally {
    }
  }
}

public class M {
  public static void Main() {}
}

It compiles, runs and verifies fine on MS.NET. 
This should be probably reported to mono as a bug.
Although if equivalent C# program compiles fine with gmcs, then we could
find out what is the difference in our usage of S.R.E. and maybe fix it.

Anyway, it needs investigation.

It seems the bug is caused by generic class initialization happenning at
the place where this is first used. This seems to require try-blocks to be
closed, and thus throws an exception.

I'll fixing it tomorrow either at our or mono side.
