Posted by developer: Thank you for the provided patch! We have checked with the provided test, and it fails on 5.6 and the provided patch makes the test pass. In 8.0 the provided test also fails, but the provided patch does *not* make the test pass. So further investigations on why it does not pass needs to be done.

Posted by developer: Fixed in 8.0.4, 9.0.0. With compression enabled for the client/server protocol, logical packets that are multiples of size 0xFFFFFF could cause the connection to be dropped. Thanks to Facebook Inc. for the patch.
