Maximum call stack size exceeded when initialValue is an array/object

bug report

What is the current behavior?

Since version 1.0.1 it seems, that values initialized with an empty array leads to a Maximum call stack size exceeded error.

What is the expected behavior?

That I can operate on this array like in version 1.0.0-alpha.1.

You can switch between the versions, which should result in the described behaviour. Could it be, that this use case handling arrays and objects should be handled differently now?

I'm getting exact same error on my application.
Does anybody know how to fix this?

@Drogglbecher, @adamklepacz, you can memoize values to avoid re-rendering component.

I faced same issue. The form infinitely re-render if I use array format in initialvalues and validator.
Took a deep look into react-final-form implementation and found they uses useConstant for validation, initialvalues, etc.
