Calculates length of std::array wrong (or not at all)

[Stefan Petersen]

Hello,

I downloaded 2.17.0 and tried it. I got a warning from cppcheck on some code that I then tried to minimize to the following:
https://godbolt.org/z/cKeEePGz4

It might be considered strange code, but it is mostly for demonstration purpose.

The length of the std::array is 6 * sizeof(uint16_t), aka 12. But cppcheck warns that the array is only 6 positions, and hence signals out-of-bounds. If I give the length of the array directly as 12, it works.

Thanks,
