  20   20  # tests using getcontextx() in lieu of the signal handler to create
  21   21  # invalid states. setcontext(2) in libc will try to kill the process if
  22   22  # this fails in most situations, so we basically go through and detect
  23   23  # that this is the case we expect (e.g. the system call returned an
  24   24  # error) and go from there.
