JVMCIRuntime::new_array_common includes a little bit of stress logic that changes how it returns when DeoptimizeALot is set. This can cause it to bypass the call to SharedRuntime::on_slowpath_allocation_exit(current) which is where the deferred card mark logic lives. This can lead to random crashes of various kinds.
