[Octave-bug-tracker] [bug #36211] bug: crashes and endless loops

[anonymous]

Follow-up Comment #6, bug #36211 (project octave):

I'm not sure. Throwing an error seems appropriate to me.
I took a look at what others do:

Scilab 5.3.3:
Scilab refuses to calculate with NaN and Inf.


-->A=[1234,%inf];b=[5];Ab;
                        !--error 229
Operands of / and  operations must not contain NaN or Inf.


MATLAB R2012a:
does not throw an error, only displays a warning (but it's somewhat
inconsistent: sometimes it doesn't even display a warning).


>> A=[1234,inf];b=[5];Ab
Warning: Rank deficient, rank = 0, tol =  1.#INF00e+00.

ans =

     0
     0


>> A=[1234,nan];b=[5];Ab
Warning: Rank deficient, rank = 0, tol = NaN.

ans =

     0
     0

>> A=[nan,1234];b=[5];Ab

ans =

         0
    0.0041



Ok ... so, it's for you octave maintainers to decide... (I'm out of here ...
after all, I just wanted to report that crash on my windows box, but soon
found myself reading fortran sources ;) )
