--- Comment #1 from ktkachov at gcc dot gnu.org ---
Confirmed. 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
