It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption to this rule, contact Hixie on the #hackers channel in Chat (don't just cc him here, he won't see it! He's on Discord!). If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix? Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. |

There was a problem hiding this comment.
I think there should be runtime warnings getting printed out if you are adding objects to the autorelease pool but there isn't one present.
If you want to add a test for this it wouldn't be that hard. In platform_message_handler_ios_test.mm you could make an NSObject that takes in a pointer to a bool and sets it's value in its dealloc. Then you can assert that dealloc was called.
