React: IE 11 console error stopping the render. `Unable to set property `nextEffect` of undefined or null reference`

Do you want to request a feature or report a bug?
Bug

What is the current behavior?
Page can't be rehydrated (but it's probably not a rehydration issue, the same happens when I use render on empty div instead). Console error:

Unable to set property `nextEffect` of undefined or null reference

(childToDelete seems to be equal undefined when I set breakpoint)
Point in source: https://github.com/facebook/react/blob/4a924a206783df5d2e06755caa0fbd2dd580b14e/packages/react-reconciler/src/ReactChildFiber.js#L243

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem via https://jsfiddle.net or similar (template for React 16: https://jsfiddle.net/Luktwrdm/, template for React 15: https://jsfiddle.net/hmbg7e9w/).
I can't isolate this bug to provide minimal demo or reliable reproduction steps without providing you the whole app. Spent a day already on this. Still trying to isolate the issue.

When I removed most (randomly choosen) components and added <div>hi</div> to render of some deep component - it was fine, but when I defined Div = () => <div>hi</div> and rendered it instead with <Div /> then I got the error. Restoring various components makes React crash on randomly looking points. Every refresh produces the same result though.

I still report it in hope some dev got an idea what could be triggering it. I'll keep looking meanwhile.

What is the expected behavior?
No errors, page should be rendered.

Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?
React 16.0.0 & 16.1.1. Windows 7, IE 11.
React 15 was working just fine.

The same is happening with development and production build.

Please provide a reproducing project.

Which Map/Set polyfill are you using? We've seen this problem with a bad polyfill before. https://github.com/facebook/react/issues/10656#issuecomment-328514056

[dzek69]

Polyfill.io

I can't pass you the whole project. If I will be able to isolate the issue in minimal code then I will surely provide it. Still working on it.

[dzek69]

I'll try with another polyfill and give you a feedback

[gaearon]

3.22 of polyfill.io is expected to have fixed this.
https://github.com/Financial-Times/polyfill-service/issues/1299

So I don't think there's anything wrong with React although I don't know why the fix didn't help for you. Maybe you're getting an old version somehow?

[dzek69]

Yeah, updating polyfill service did the job.

So you're right, that's not React bug.

Thank you for your help, I wasn't able to find the linked issue via search bar or Google. I hope having error in the issue title will be enough for others to find it if needed.
