CodePlex Issue #33341 Plain Text Attachments

description.txt

I've found a problem that only seems to happen when importing from a pyc compiled assembly, but does not show when importing the script directly. Attached is as far as I have managed to reduce a simple test case to (I first came across this in SQLAlchemy).

Running directly (or, opening the repl and then importing manually):
$ ipy testipy.py

Works fine, but compiling with pyc (assuming you have an alias):
$ pyc /out:TestIPy testily.py

And then running the script:
import clr
clr.AddReferenceToFileAndPath("TestIPy.dll")
import testipy

Gives the following traceback:

Traceback (most recent call last):
