You may want to look at the recent BIND 9 source:
lib/isc/backtrace.c
lib/isc/include/isc/backtrace.h
(even in NetBSD src/external/bsd/bind/dist/)

It has comments and embedded docs explaining it. It provides examples 
using backtrace() and gcc's Unwind_Backtrace() (on x86_64 or IA64). So 
yes it is machine dependent.
