Can you please attach the debugger log (contents of right pane of
Windows->Views->Debugger Log), either here, or to a report at
bugreports.qt.io

I can't reproduce this with e.g.

    #include <vector>

    struct Foo { int z; };

    int main()
    {
        std::vector<Foo> f = { {1}, {2}, {3} };
        for (auto & x : f)
            ++x.z;
    }
