   8 GFORTRAN_ERROR_BACKTRACE---Show backtrace on run-time errors
   9 ************************************************************

  11 If the :envvar:`GFORTRAN_ERROR_BACKTRACE` variable is set to :samp:`y`,
  12 :samp:`Y` or :samp:`1` (only the first letter is relevant) then a
  13 backtrace is printed when a serious run-time error occurs.  To disable
  14 the backtracing, set the variable to :samp:`n`, :samp:`N`, :samp:`0`.
  15 Default is to print a backtrace unless the :option:`-fno-backtrace`
  16 compile option was used.
