Swift interpreter error when loading Python library

[davidcittadini]

I am trying the Swift interpreter with Swift for TensorFlow. I have created a simple test file as follows. with the latest versions of matplotlib and librosa installed:

#!/usr/bin/env swift
import TensorFlow
import Python
let np = Python.import("numpy")
let plt = Python.import("matplotlib.pyplot")
let librosa = Python.import("librosa")

When I run this with Swift I get the error message:

Assertion failed: (PassInf && "Expected all immutable passes to be initialized"), function addImmutablePass, file /Users/buildbot/miniconda3/conda-bld/llvmdev_1530886763012/work/lib/IR/LegacyPassManager.cpp, line 755.

If I remove the librosa library then the error goes away.

My current versions are:

Swift: version 4.2-dev (LLVM d1ad27a0c9, Clang 528407c5c8, Swift ac63360ffc)
macOS: Version 10.14.2 Beta (18C38b)
Xcode: Version 10.1 (10B61)
Swift for TensorFlow: DEVELOPMENT-2018-10-17

I am unable to reproduce it. It may have been fixed by our last merge from Swift upstream. If the issue persists for you, please reopen this issue. Thanks!
