make[4]: *** [test-stdalign.o] Error 1
The code which fails is a macro that expands to:
typedef struct { char slot1; int64_t slot2; } int64_t_helper;
verify (alignof (int64_t) == offsetof (int64_t_helper, slot2));
/*...*/
typedef struct { char slot1; double slot2; } double_helper;
verify (alignof (double) == offsetof (double_helper, slot2));
I printed out the actual numbers and they are:
alignof (int64_t) = 8
offsetof (int64_t_helper, slot2) = 4
alignof (double) = 8
offsetof (double_helper, slot2) = 4
