[IronPython] Very strange problem with ExecuteFile

I believe in this case the exception is result of what seems to be a CLR limitation. The code (in this case one static method) IronPython needs to generate to handle this input is too big and CLR/Jit then throws invalid program exception.

The only workaround I am aware of is to split the code up to multiple functions.

Subject: [IronPython] Very strange problem with ExecuteFile

When the attached test.py is executed using ExecuteFile (sample .cs file also attached), we get the following exception:

    System.InvalidProgramException: Common Language Runtime detected an invalid program.

The problem does not occur under the IP Console (which I guess doesn't use ExecuteFile).  My best guess is that the problem occurs when the complexity of the parse tree exceeds some particular limit.

Does anyone have any ideas for a workaround or a fix?  This one is causing us serious problems, so any thoughts would be much appreciated.
