   library will call malloc as it works, 0 if it will call mmap

   the backtrace functions from a signal handler.  In general this
   only applies to calls like backtrace and backtrace_pcinfo.  It does
   not apply to backtrace_simple, which never calls malloc.  It does
   not apply to backtrace_print, which always calls fprintf and
   therefore malloc.  */
