It's also raised in some "more common" scenarios, such as misaligned
memory access, or access beyond the end of a memory-mapped file. Maybe
qemu is allowing an unaligned access that the native CPU would
disallow for some reason. If I'm not mistaken, delivery of SIGBUS is
also synchronous, so getting a backtrace and a register dump at the
crash site should help.
