This was pulled up at a code review. Code was similar to this:

struct foo {
  int bar;
  int baz;
} f;

int * i = (int *) f;

The only way this could go wrong is if the struct contains padding before 
its first member, but I don't think this would ever happen in practice 
--- maybe on theoretical perverse implementations like the ones you guys 
like to play with :)

Who is right here by the letter of the law?

Cheers
Edward
