This doesn't make a great deal of sense to me.  There's no sign of the
SIGBUS being delivered between the read() and sigaction().  The latter
is in sigpanic() and so must be after the SIGBUS was received.  There
are also two SIGBUS reports.  I suspect that truss is getting confused
and not reporting things in the correct temporal order.

Your best bet might be to capture a core file or run the code in a
debugger and try and get a backtrace.  This would at least give you
a pointer to where the SIGBUS is being generated.
