Problem
When a device is in the process of being commissioned but the operation node discovery timeouts there is a
use-after-free
because the failure callback release the actualOperationDeviceProxy
before callingCommissioningStageComplete
that is trying to use it.Change overview
CommissioningStageComplete
has been called.Testing
I have tested it by modifying the mdns code on darwin to advertise the operational data after a delay longer than the one use by the commissioner.
