I actually follow the sizeof(variable) when the variable is not a pointer
type almost always because I've made the mistake before of changing the
type of a local variable, and not updating the sizeof(Type) next to it in
a memset, etc.
Of course, for pointer types, when you want the size of the thing pointed
to, I always use sizeof(Type) because sizeof(pointer) will obviously give
the wrong answer.
I know it is an inconsistent ruleset when compared to each other, but when
applied consistently throughout my code it has caught/prevented bugs from
shipping.
Or are you thinking of a different case where the compiler does the wrong
thing independent of human error?
