What happens if you have compiled with "-g3", have the line

#define STOP abort ()

in your code and the mouse hovers over STOP?

Also do the values of large arrays/structures appear as large tooltips?

Around the end of last year there was a discussion on gdb-patches (Re: variable
objects and registers) about using variable objects for tooltips.  Jim
Ingham said that Apple currently do this for Xcode and it works well.  I think
we should explore this possibility and perhaps review their code.
