Check out "man 7 signal." Unless they semantics have changed, sigbus is not
supposed to generate a core dump:

SIGBUS 10,7,10 AG Bus error

A Default action is to terminate the process.
C Default action is to dump core.
G Not a POSIX.1 conformant signal.

That is probably why you didn't get the core dump. . .
