I've had a go at producing an example too with no luck. The Constant involved on the breaking config is ridiculously complex (even after reduction): `i32 or (i32 shl (i32 or (i32 shl (i32 or (i32 shl (i32 and (i32 ptrtoint ([19 x i8]* @0 to i32), i32 63), i32 8), i32 and (i32 lshr (i32 ptrtoint ([19 x i8]* @0 to i32), i32 6), i32 63)), i32 8), i32 and (i32 lshr (i32 lshr (i32 ptrtoint ([19 x i8]* @0 to i32), i32 6), i32 6), i32 63)), i32 8), i32 lshr (i32 lshr (i32 lshr (i32 ptrtoint ([19 x i8]* @0 to i32), i32 6), i32 6), i32 6))`

And since the change is obviously right, I think you should go ahead.
