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.
