Webstorm EAP 2018.3 hanging when trying to analyze redux code

Hi there,

For the last couple of EAP builds at least, I have been experiencing hanging/high CPU usage when WS tries to analyze redux reducer (with reselect) modules, it never finishes analyzing and it shows spurious false errors.

It is 100% repeatable for me.

The project is a React-Native app and I'm running on MacOS Mohave on a 15" 2018 MacBook Pro with 32GB.

Please let me know if I can provide anything to help you resolve this issue!

Please provide your log folder (~/Library/Logs/WebStorm2018.3) content. Project that shows up the issue would be appreciated

Hi Elena,

Here are the requested logs and a sample project with the minimum source that exhibits the problem (open gallery.js, and it never finishes analysis)

PS. this is just a snippet from one file that is causing the issue, it's present in a number of other files in my actual project but all of them are redux reducers using immutable.js

PS. I have downgraded to webstorm 2018.2.5 and the issue is not present in this version.
