  Log Message:
  -----------
  [sanitizer-common] [Darwin] Provide warnings for common sandbox issues (#165907)

We currently do not handle errors in task_set_exc_guard_behavior. If
this fails, mmap can unexpectedly crash.
We also do not currently provide a clear warning if no external
symbolizers are found.
