The alias set is the same:
(insn:TI 2204 2201 78 pr37408.i:9124 (set (reg:DI 6 6)
(zero_extend:DI (mem/c/i:SI (plus:DI (reg:DI 5 5 [6])
(const_int 1492 [0x5d4])) [5 nargs+4 S4 A64]))) 14
{*zero_extendsidi2_internal1} (nil))
(insn:TI 68 82 69 pr37408.i:9114 (set (mem/c/i:DI (plus:DI (reg:DI 5 5)
(const_int 1488 [0x5d0])) [5 nargs+0 S4 A64])
(reg:DI 3 3 [ nargs+-4 ])) 337 {*movdi_internal64} (expr_list:REG_DEAD
(reg:DI 3 3 [ nargs+-4 ])
(expr_list:REG_EQUIV (mem/c/i:DI (plus:DI (reg/f:DI 67 ap)
(const_int 48 [0x30])) [5 nargs+0 S4 A64])
(nil))))
Perhaps MEM_SIZE in second insn (originally first) being only 32-bit and not
64-bit is the bug.
