  # When we switch from Ubuntu 16.04 to 18.04, we found that running with the address sanitizer,
  # the pthread_create function calls were not working. The inital thought was that we were
  # trying to create a thread that was not-blocking and would eventually crash the machine during
  # the run. After more debugging, we found that we would never even start the thread. We narrowed
  # down the first two instances of pthread_create in the gNB and NR UE to be sctp_eNB_task and
  # one_thread, respectively. We found that adding sleeps, and various other pauses to the threads
  # had not effect. From there, we found that if we add an abort(); prior to the thread loop, we
  # do not execute that. This indicated to us that the problem is not likely to be a non-blocking
  # thread, but perhaps and issue with pthread_create itself. From there we begain to research the
  # issue on the web. See: https://github.com/google/sanitizers/issues/1125
  #
  # Google searching indicates this appears to be a problem since at least 2018. This could be something
  # wrong in the pthread library, or something subtly wrong in this CMakeLists.txt. Use Ubuntu 20.04 instead.
