I don't think that casting a range of bits as some other arbitrary type "is a bug nobody sees coming".
C++ compilers also warn you that this is likely an issue and will fail to compile if configured to do so. But it will let you do it if you really want to.
That's why I love C++
Ignoring warnings is really not a good way to deal with it. If a compiler is bitching about something there is a reason to.
A lot of times the devs are too overworked or a little underloaded in the supply of fucks to give, so they ignore them.
In some really high quality codebases, they turn on "treat warnings as errors" to ensure better code.
I know that should be the philosophy, but is it? In my experience it seems to be normal to ignore warnings.
