As I recall, this code is supposed to set the segmentation fault handler, then 
use __builtin_return_address() with increasing values until it hits a segfault, 
and then catch the fault, jump out, and only use the previously-collected 

Your back trace in gdb is what I'd expect, but you need to hit c because gdb 
will stop on any signal, even if it's one that is handled sensibly.  If this is 
really where it's crashing, then it means that the signal handler is not being 
correctly set, but it's probably crashing somewhere later.
