Sorry just saw it came with some examples. Testing with the `lookupdns' program ended with a Bus error (core dumped). Here is gdb output:
Core was generated by `lookupdns'. Program terminated with signal SIGBUS, Bus error. #0 _longjmp () at /usr/src/lib/libc/arch/amd64/gen/_setjmp.S:99 99 1: movq %r11,0(%rsp) (gdb) bt #0 _longjmp () at /usr/src/lib/libc/arch/amd64/gen/_setjmp.S:99 Backtrace stopped: Cannot access memory at address 0xb044815db732800f
