display of instance vars

[Leland Hovey]

When I display an object's instance var with gdb (Linux), I receive 
the following error message:

"Evaluation of this expression requires the program to have a function
'objc_lookup_class'".

The gdb command:
>print ivar

I realize I could find "ivar's" value with the command "print
*self" but in some cases this displays too much information.

In addition, "print *self" doesn't display nested structures.

And, "print self->ivar" gives the same results as "print ivar".

Would you know what the problem is here and is there a quick
fix?  (gdb without objective-c capability?) (Is this Swarm
related?)

thanks,
Leland H.
