Yes it is standard behavior, and ObjC does ignore a message to a nil 
object and just returns 'NULL'. The problem is Solaris chokes when you 
try to assign a 'NULL' to a structure. Even this should crash Solaris 
(if you could actually compile it, which you can't since the compiler 
is smart enough for this):

struct foo {int i; int j;};

struct foo bar;

bar = (struct foo)0;
