Ah, I see what you mean. Yes, you are right.
That came out of some macro expansion.
Unfortunately I can still see the problem in the
location list when I reference the array elements
without the casts:
_Log("abc",
(__FUNCTION__+((__FUNCTION__[(sizeof("FSS") - 1)] == '_') ?
(sizeof("FSS") - 1) + 1 : (sizeof("FSS") - 1))),
237 , (p1)->f1, (p1)->length,
p1->data[0], p1->data[4], p1->data[8],
p1->data[12], p1->data[16], p1->data[20],
p1->data[24], p1->data[28], p1->data[32],
p1->data[40], p1->data[48], p1->data[56], p2);
