<pre>I suspect this bug has been around for a while but hasn't been caught because
the bots all set LLVM_ENABLE_ASSERTIONS to True. The bug only reproduces when
LLVM_ENABLE_ASSERTIONS is not set (or is set to False). We can confirm that
this fails on Windows Server 2016/Windows 10 when running with Python 2.7 or
Python 3. Here are example CMake options from a failing build on Windows Server
2016:
-DPYTHON_HOME=C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python36_64
-DCMAKE_BUILD_TYPE=release
-G Visual Studio 15 2017 Win64
-Thost=x64
Here is the log from the failure:
