Yup.
debug_rtx(out_rtx) = (mem/f:DI (plus:DI (reg/v/f:DI 164 [orig:129 p ] [129])
(const_int 16 [0x10])) [4 p_8(D)->d3+0 S8 A64])
debug_rtx(in_rtx) = (reg/v/f:DI 151 [orig:129 p ] [129])
Because in_rtx doesn't appear in out_rtx the condition "regno_use_in (REGNO
(in_rtx), out_rtx) == 0" misses its mark.
