Repro steps

In the example,

  const restart = React.useCallback(() => {
    if (observable) {
      setObservable(recreateRef.current());
    }
  }, [observable]);

should be fine, but the compiler complains that setObservable is missing from the dependency array, even though it is aReact.useState return value from the same hook.

The inferred dependency was setObservable, but the source dependencies were [observable]. Inferred different dependency than source.

Apologies for the weird reproduction - I couldn't reproduce this from scratch, so it's a minimized variant of where we're seeing this in the wild: https://github.com/apollographql/apollo-client/blob/a43583377ccaae60b58bc45edfc88f32bed74a46/src/react/hooks/useSubscription.ts#L375

I know that on it's own, the reproduction doesn't make a lot of sense, but if I leave any of the leftover building blocks out, everything works nicely.

How often does this bug happen?

Every time

What version of React are you using?

19.1.0, but likely irrelevant - this is a library with peerDependency 17-19

What version of React Compiler are you using?

1.0.0/playground

firstly, complete build in your branch:

recreateRef.current = recreate;
setObservable(recreateRef.current());

Censured, this isn't working

Functional programming:
{...JSON}>>>json();
(FileName) => return browser_function();
It's sand CPU. We don't use chemistry in this case and hardware doesn't have a form to execute the property correctly.
Hook object inside a state:
Let state = {"potatoe"};
If (state === "potatoe"){state = "onion";}
//render state
React.fragment(){return(

{state}

);
