This looks pretty weird: alignof_slot (char) and offsetof (char_helper, slot2) should be different?? Where alignof_slot (char) is defined as offsetof (struct { char __slot1; char __slot2; }, __slot2) and char_helper is defined through typedef struct { char slot1; char slot2; } char_helper; The only differences between the left-hand side and the right-hand side are the names of the struct fields, and the use of 'typedef'. You need to look at the preprocessed output (cc -E) of test-alignof.c and trim it down to produce a minimal test case. Bruno
