Update of bug #54094 (project octave):

                  Status:                    None => Invalid                
             Open/Closed:                    Open => Closed

Follow-up Comment #2:

I agree with comment #1, it appears that you have merely created an infinite
loop.  Try this code on the command line.


octave:1> x = 1;
octave:2> while (x = 0)
> x++;
> endwhile
warning: suggest parenthesis around assignment used as truth value
octave:3> 


The first time through the loop x is assigned the value of 0 and "while (0)"
is false so the loop stops immediately.

On the other hand, if the assignement (=) creates a true value then the loop
is infinite.  I used a Ctrl+C to break the loop.


octave:3> x = 1;
octave:4> while (x = 1)
> x++;
> endwhile
warning: suggest parenthesis around assignment used as truth value
^C
octave:4>
