[MonoDevelop] exception thrown with simple VBA program

[Clark linuxguy]

I wrote a simple program for calculating factorials:
http://codepad.org/49XoUmJw
It compiles file with vbnc
when I run it it crashes with an exception:

./factorial.exe
Unhandled Exception: System.InvalidProgramException: Invalid IL code in
Application:Main (): IL_0000: ldarg.0

Does anyone know what is wrong or how to fix it?

I am using vbnc version 0.0.0.5917
