There was a problem hiding this comment.
From what I've seen there is at least one element in the range:
TxSpends::iterator it = range.first;
const CWalletTx* copyFrom = mapWallet[it->second];
for (; it != range.second; ++i) {
...Maybe this assert should come first:
assert(range.first != range.second);There was a problem hiding this comment.
That would not suffice to silence the analyzer, because copyFrom is also nullptr if the range is nonempty but n == nMinOrderPos in every iteration.
