I think the bug is in combine.c (force_to_mode).
force_to_mode (
(subreg:DI (ior:SI (lshiftrt:SI (reg:SI 125)
(const_int 31 [0x1f]))
(subreg/s:SI (reg:DI 134 [ iftmp.1 ]) 4)) 0)
, DImode, 3, 0, 0)
returns
(ior:DI (lshiftrt:DI (subreg:DI (reg:SI 125) 0)
(const_int 31 [0x1f]))
(reg:DI 134 [ iftmp.1 ]))
