I'm rather new to Objective-C and Cocoa/GNUStep programming, but is this the standard behavior?

I thought, that messages sent to nil objects should be silently ignored by the Objective-C runtime system. Am I missing something?


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;
