@section @env{GFORTRAN_ERROR_DUMPCORE}---Dump core on run-time errors
If the @env{GFORTRAN_ERROR_DUMPCORE} variable is set to
@samp{y}, @samp{Y} or @samp{1} (only the first letter is relevant)
then library run-time errors cause core dumps. To disable the core
dumps, set the variable to @samp{n}, @samp{N}, @samp{0}. Default
is not to core dump unless the @option{-fdump-core} compile option
was used.
@node GFORTRAN_ERROR_BACKTRACE
@section @env{GFORTRAN_ERROR_BACKTRACE}---Show backtrace on run-time errors
If the @env{GFORTRAN_ERROR_BACKTRACE} variable is set to
@samp{y}, @samp{Y} or @samp{1} (only the first letter is relevant)
then a backtrace is printed when a run-time error occurs.
To disable the backtracing, set the variable to
@samp{n}, @samp{N}, @samp{0}. Default is not to print a backtrace
unless the @option{-fbacktrace} compile option
was used.
