It is actually:
dataflow difference found: old and new follow:
 (value/s/u:DI 54:54 @0x42b02e8/0x42a75c8)
    offset 0
      (mem/f:DI (value/s/u:DI 56:56 @0x42b0308/0x42a7578) [161 S8 A64])
      (value/u:DI 90:90 @0x42b06b8/0x41569c0)
 (value/s/u:DI 54:54 @0x42b02e8/0x42a75c8)   
    offset 0
      (mem/s/f:DI (value/s/u:DI 54:54 @0x42b02e8/0x42a75c8) [161
<variable>.next+0 S8 A64])
      (mem/f:DI (value/s/u:DI 56:56 @0x42b0308/0x42a7578) [161 S8 A64])
      (value/u:DI 90:90 @0x42b06b8/0x41569c0)
alternating, it is quite weird that value 54 is in (mem (value 54)), guess need
to find out in detail what's going on.
