Your running this under a Xen domU right?
You could try the i386 versions to see, but I wouldn't be surprised
if you end up with the same results.
Instead of a domU why not try running it out of an HVM which performs
greater level of abstraction. IF heartbeat is trying to use the low
level features of the network interface then that may be the reason
it is segfaulting in the para-virtualized machine.
