Error with undefined __hooks property

Hi,

sorry for this confusing issue, but I haven’t found anything so far:

I have the issue that __hooks is suddenly undefined:

Both of the forEach before succeed, but here __hooks is suddenly undefined (ie it must be through a side effect of one the invokeEffect calls):

Error in console:

My hooks.module.js (extended by some console.log() calls):

I highlighted the one that is right before the error.

The component that is triggering this error seems innocent enough (it is not yet finished 😉):

Happy to provide any additional info, if you could give me some pointers on where to look.

Ok wow, so I finally got it reproducible. (I don’t want to admit that finding this just took me around 4.5 hours 😬)

Please, before investing time into “fixing this”: if my code / architecture is 💩 (ie that is a “won’t fix”), please tell me beforehand so that I can clean it up on my side and you don’t have to support super obscure use cases. 😬

Here is the reproducer: https://codesandbox.io/s/mystifying-frost-u6b7v

1. pass a state hook setter into a nested prop
2. immediately call this setter synchronously
3. in the inner element render something (somewhere else using render()) in an effect.

I have absolutely no idea what is happening here, but what I can tell you is:

• if move the render() code outside of the useEffect it works.
• if I remove the state hook setter call it works

I guess step 2 is not supposed to be done like this, but I actually have no idea anymore now 😄

@apfelbox I put up a PR that is aimed at fixing this issue. Sorry I totally missed that repro
