[IronPython] irc.rb

[Tomas Matousek]

Right. This is the error Dino overheard me talking about :) As you can see from the stack trac, something seems to be broken in DLR. I'll look at it and see whether I can come with a simple fix. Precompilation is currently P2 on our task list though, so I'm afraid any more complex work would need to wait until P1's are done.

Hi, I've created an irc.rb (attached) which mimics IronPython's pyc.py. It is failing on this line:

Microsoft::Scripting::ScriptCode.save_to_assembly(outfile, codes.to_array())

With the following exception... Any help would be greatly appreciated. The test file I'm trying to compile is also attached. I am building on revision 140. I have also tried with the Microsoft.Scripting and Microsoft.Scripting.Core dlls from IronPython with the same result.
