[Octave-bug-tracker] [bug #46660] object array writing into class member alters another class member

[Lachlan Andrew]

Update of bug #46660 (project octave):

                Severity:           4 - Important => 3 - Normal

Follow-up Comment #1:

For those wishing to repeat this, you can cut-and-paste the following.


clear all;
clear classes;
a(1)=testclass;
a(2)=testclass;
a(2).x = 123;
display(a(2).x);

%123

display(a(2).y);

%[](0x0)

a(2).y = 321;
display(a(2).x);

%[](0x0) <----- writing into a(2).y has altered a(2).x

display(a(2).y);



Note that if this is placed into a script and executed, then it works
correctly:


octave:14> testclasstest
 123

[](0x0)

 123

 321


The fact that it works in a script makes the severity of this problem much
less than it would otherwise be.
