    auto src = instr->psrc(0);
    auto dest = instr->dest();

-   for (auto& i : instr->dest()->uses()) {

       /* SSA can always be propagated, registers only in the same block

The change seems to be a result of the previous assignment to dest, but it may
be important to call instr->dest() with for here.
But I don't know about C++ :)
