x86_64, PostgreSQL 9.2. is run within an OpenVZ container and generates SIGBUS.
PostgreSQL 9.1 has no such problem.

(OpenVZ is a linux kernel-level virtualization which adds namespaces for processes, networking, quotas etc. It works not like e.g. Xen or VMWare, because all containers share the same kernel.)

for posterity, what's the hardware platform?  software bus errors are
more likely on non x86 hardware.
