Description:
        At line 209 of execute_cmd.c is this code:

      if (currently_executing_command->type == cm_simple)
        return currently_executing_command->value.Simple->line;
      else if (currently_executing_command->type == cm_cond)
        return currently_executing_command->value.Cond->line;
      else if (currently_executing_command->type == cm_arith)
        return currently_executing_command->value.Arith->line;
      else if (currently_executing_command->type == cm_arith_for)
        return currently_executing_command->value.ArithFor->line;
      else
        return line_number;

but the Cond, Arith, and ArithFor members are undefined if the
respective feechures are configured out.

Fix:
        Add conditionals like this:

      if (currently_executing_command->type == cm_simple)
        return currently_executing_command->value.Simple->line;
#ifdef COND_COMMAND
      else if (currently_executing_command->type == cm_cond)
        return currently_executing_command->value.Cond->line;
#endif
#ifdef DPAREN_ARITHMETIC
      else if (currently_executing_command->type == cm_arith)
        return currently_executing_command->value.Arith->line;
#endif
#ifdef ARITH_FOR_COMMAND
      else if (currently_executing_command->type == cm_arith_for)
        return currently_executing_command->value.ArithFor->line;
#endif
      else
        return line_number;
