The line that seems to be causing this is
new StoreInst(store->getValueOperand(), shadow, &*i);
where
store and i are Instructions, i being what I'm looping over
shadow is a new GlobalVariable I created. I also made a new
section for it to be in.
Does this help any? I don't understand the significance of this line,
all looks fine to me still.
