Thank you!

We rely on Object.freeze in our tests a lot and are suffering from this bug. It's amazing to see it fixed, is there any chance there will be a release soon?

[gaearon]

Just a heads up we'll need to revert the upgrade and downgrade to 24 in the meantime.

What happens in this fix if the object has a setter that throws or causes a side-effect (e.g. logs)?

[gaearon]

Filed an issue for setters. #9745
