--- Comment #1 from Sergio Martins <smart...@kde.org> ---
This is not a false positive, check
https://code.woboq.org/qt5/qtbase/src/corelib/tools/qhash.h.html#_ZNK5QHash4keysEv
to see how keys() is implemented, it allocates and fills a new container
There's no easy way, but you could do:
bool keysEqual(const QMap<int, QString> &map1, const QMap<int, QString> &map2)
{
if (map1.size() != map2.size())
return false;
for (auto it1 = map1.keyBegin(), it2 = map2.keyBegin(), e1 = map2.keyEnd();
it1 != e1; ++it1, ++it2) {
if (*it1 != *it2)
return false;
}
return true;
}
Which is a couple orders of magnitude faster
