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++
Ideally? Zero. I’m sure some teams require “warnings as errors” as a compiler setting for all work to pass muster.
In reality, there’s going to be odd corner-cases where some non-type-safe stuff is needed, which will make your compiler unhappy. I’ve seen this a bunch in 3rd party library headers, sadly. So it ultimately doesn’t matter how good my code is.
There’s also a shedload of legacy things going on a lot of the time, like having to just let all warnings through because of the handful of places that will never be warning free. IMO its a way better practice to turn a warning off for a specific line.. Sad thing is, it’s newer than C++ itself and is implementation dependent, so it probably doesn’t get used as much.
Yeah, I’ve seen that too. The problem is that once the library starts spitting out warnings it’s hard to spot your own warnings.
Yuuup. Makes me wonder if there’s a viable “diaper pattern” for this kind of thing. I’m sure someone has solved that, just not with the usual old-school packaging tools (e.g. automake).
