It's probably worth noting that the disambiguated MEMs are of different widths:
> load from "(mem/c/i:DI (reg/f:DI 14 r14 [351]) [2 t+8 S8 A64])"
> store to "(mem/s/j/c:SI (reg/f:DI 15 r15 [343]) [2 t+4 S4 A32])"
(btw, IIUC the above mems do not alias indeed, and the problem is in
disambiguating the above store and a load from
(mem/c/i:DI (post_inc:DI (reg/f:DI 14 r14 [351])) [2 t+0 S8 A128]) )
Also, with -fno-strict-aliasing the failure vanishes.
