Looks like a bug in in the length calculation of some insns to me. Compiling with -dp shows that GCC thinks insns like ldrsh r2, [r4] @ unaligned @ 168 unaligned_loadhis/1 [length = 2] have length 2 when in fact only register offset LDRSH can have length 2. So we underestimate them and cause this error
