Changes to the information printed when a signal occurs:

Просмотр исходного кода 
* Have darwin backtrace code return an error when buffer() is
    called, since it is not imnplemented
  * Print out hostname & pid when giving signal information
  * If backtrace_buffer() is implemented, use that instead of
    backtrace_print() and prefix stacktrace with the hostname
  * Make the signal information printed be more user friendly
  * If we're using the backtrace_buffer() code, don't print 
    the last two functions (which will be show_stackframe()
    then backtrace_buffer()) so that users won't keep thinking
    the error occurred inside Open MPI (sneaky, yes...)
