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.
