RE: [sv-ec] copy constructor on handle pointing null

Daniel,

 

Calling the copy constructor with a null object should trigger a
run-time error. The LRM does state that the class properties and
internal state must be copied - and that will definitely triggers an
error.

Subject: [sv-ec] copy constructor on handle pointing null

 

LRM doesn't describe what should happend if handle which we are trying
to copy is equal null like in sample below. Should it trigger runtime
error that this is illegall null refrence, or should it silently assign
destination hadle with null ( performing no allocation)?

 

module top; 
 class C;
  int a;
 endclass 

 C c1,c2 ;
 initial begin
     c1 = new c2;    
 end
endmodule
