Crash in CoUnitialize when using UI Automation

[Alan Martin IRL]

Hi,

We have a large MFC application. We are currently going though the process of updating our compiler from MSVC 2013 to MSVC 2017, and MFC from version 120 to version 140.

Unfortunately, we are seeing a crash on shutdown whenever any tool is controlling the application using the UI Automation API.


The stack trace is below, any help would be appreciated.
