This value of 'mem' is unaligned, explaining the SIGBUS.

If it had been aligned, a SIGSEGV would have been generated, and
libsigsegv's handler would have been triggered. But since even after
filling in a memory page an unaligned address remains an unaligned address,
it would have been pointless to invoke libsigsegv's handler. So, there
is no need to change libsigsegv.
