The problem is that it doesn't crash on my G5 nor on my iBook G4. It  
only crashes on some people's systems. And it crashes very deep  
inside calls below carbon actually, in CoreGraphics, while  
constructing some font path (the above crashlog doesn't even mention  
Carbon, but the previous GUI hello-world crash logs did, which is why  
I was talking about Carbon all the time).

You'd have to wrap anything which will potentially draw a glyph on  
screen. That's not feasible, I think.
