I have now managed to indeed get a SIGBUS on a Raspi4 by running 32-bit code that uses ldrd with an unaligned address (but regular ldr does not produce such an exception). So SSE/SSE2, ldrd (and friends) are the last die-hards in a general-purpose world dominated by instructions that work with unaligned addresses.
