Of course they know, but they still warn about it.

Maybe, but the compiler won't take that into consideration. I did look
at some of the warnings, and I can confirm that the code is safe.
However this is still risky in the future IMO.

Ok, I accept that OCRAD is part of a conspiracy to establish the new gnu
world order and won't bother you with warnings again :-)
