--- Comment #6 from kal.conley at dectris dot com ---
We are hitting this warning too with:

#include <stdint.h>
#include <vector>

int main() {
    std::vector<uint64_t> inputs(2);
    std::vector<uint8_t> outputs{inputs.begin(), inputs.end()};
    outputs.back() = 1;
    return 0;
}

Regards,
Kal
