This seems to be a cse problem.  The code looks like

(set (reg:si 124) (reg:si 5))
...
(set (reg:si 5) (reg:si 124))
...
(set (reg:di 119) (reg:di 5))
...
(set (reg:di 3) (reg:di 119))

cse propagates the value of reg:si 5 to the last insn

(set (reg:di 3) (reg:si 5))

Which is incorrect since the hard reg is accessed in a different
mode.
