[IronPython] 2.0 beta3: with statement: SystemError: Operation could destabilize the runtime.

-X:ExceptionDetail is usually much more useful - we should probably just kill -X:ShowClrExceptions :).

That exception isn't coming from IronPython -- not directly, anyway.  Can you re-run with the -X:ShowClrExceptions flag?

Have you done anything to force IronPython to run as a 32-bit app or is it running as a 64-bit app (ie natively)?  Is MPI.NET<http://MPI.NET> built against CLR 2.0?

I used IronPython 2.0 Beta3 using the with statement. I got the following error:

>ipy.exe a.py
Traceback (most recent call last):
  File "a.py", line 17, in a.py
SystemError: Operation could destabilize the runtime.

What I did:
1) create a __future__.py file with 1 line:

2) run the following script. the error occured in the line "with MPI.Environment(argarrayref) as mpienv:"

from __future__ import with_statement
import sys
import clr
import System

sys.path.append("C:\Program Files (x86)\MPI.NET<http://mpi.net/>\Lib")
import MPI

argarray = System.Array[str](sys.argv)
argarrayref = clr.Reference[ System.Array[str] ]( argarray )
with MPI.Environment(argarrayref) as mpienv:
Question: how can I fix it? thanks,
