Error code 2 is KERN_PROTECTION_FAILURE, most likely writing to read-only memory. You should also print the faulting instruction address (scp->sc_eip) and the faulting address (sigcode). See how it's done in the error () call above. It would be easier for you to debug if you add an infinite loop after the fprintf, so the system would just hang at that point. Then you could attach GDB and inspect things. Sergey
