[Octave-bug-tracker] [bug #65712] sort over InF dimension coredumps

[Arun Giridhar]

Follow-up Comment #5, bug #65712 (group octave):

>From ov-base.cc:

int
octave_base_value::nint_value (bool frc_str_conv) const
{
  double d = 0.0;

  try
    {
      d = double_value (frc_str_conv);
    }
  catch (octave::execution_exception& ee)
    {
      err_wrong_type_arg (ee, "octave_base_value::nint_value ()", type_name
());
    }

  if (octave::math::isnan (d))
    error ("conversion of NaN to integer value failed");

  return static_cast<int> (octave::math::fix (d));
}


It is checking only for isnan not isinf, so the fact that Clang is lumping inf
with nan might be a Clang bug.

Either way, we need better safeguarding against inf inputs causing crashes.
