Please CC 85445@bugs.debian.org on replies] According to the documentation, : When the operand of `__alignof__' is an lvalue rather than a type, : the value is the largest alignment that the lvalue is known to have. : It may have this alignment as a result of its data type, or because it : is part of a structure and inherits alignment from that structure. For : example, after this declaration: : : struct foo { int x; char y; } foo1; : : the value of `__alignof__ (foo1.y)' is probably 2 or 4, the same as : `__alignof__ (int)', even though the data type of `foo1.y' does not : itself demand any alignment. However, $ cat a.c #include #include int main() { struct icmp foo; printf("%d\n", __alignof__(foo.icmp_dun)); printf("%d\n", __alignof__(foo.icmp_data)); return 0; } $ make a cc a.c -o a $ ./a 4 1 $ where struct icmp is defined as, struct icmp { u_int8_t icmp_type;
