Subject: Fix a potential use-after-free in ATC code
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=a972df05dc643f4c944127596da403d23df7b876;p=flightgear.git

Fix a potential use-after-free in ATC code

- when dynamics shuts down the ATC controllers, they clear their
  traffic vectors (destroying the records), but we didn’t notify
  the AI aircraft of this. Ensure the controller is cleared so
  the AI aircraft shutdown doesn’t crash.
