>Environment:
sparc-sun-solaris2.5.1
>Description:
A pointer to a class object is created by calling new.
After some time, it is destroyed by calling delete. However,
data members of the class are still accessible via member
functions (called on the deallocated pointer). Trying to
access deallocated memory should give a core dump. Nothing
of the sort happens. The program runs normally.
>How-To-Repeat:
Just compile and run the file using:
% g++ test1.ii
% a.out
