In which case would an arbitrary pointer casting be a problem ?

Roughly all of them. The real question is how violently the
problem will show itself. Some of them can lie dormant for a
decade before a platform change exposes them as total show-stoppers.

With any byte addressable architecture, a pointer is just a pointer.

But there are quite a few non-byte addressable architectures out
there. Including ARM, last I checked.

In C, a byte is just the smallest addressable memory unit. It must
hold at least 8 bits, but it can be many more.
