The sanitizer code triggers this warning for code that looks conceptually like
this:
typedef struct Bla { char bar; int foo; } __attribute__((packed));
uintptr_t getu(struct Bla *b) { return (uintptr_t)&b->foo; }
Resulting in:
taking address of packed member 'foo' of class or structure
'Bla' may result in an unaligned pointer value
[-Waddress-of-packed-member]
Of course the warning can be silenced with `return (uintptr_t)(char*)&b->foo;`
still casting to an int type seems like a benign case for this warning so maybe
we should exclude that?
