the bug is in sizeof(element) - i've made unlucky structure, some
time ago, where sum of sizeof(each_element) gives size of 14 and
sizeof(whole_struct) returns 16. on old gcc-2.9.x there was the same
problem.
as an example program i've wrote shor one, that shows sizeof() from
struct having 14 char's table, 'unlucky' struct and sum of all elements sizes.
// sizeof(a)==16B instead of 14B...
struct a
{
char bfType[2];// 2B
unsigned long bfSize;// 4B
unsigned short bfReserved1;// 2B
unsigned short bfReserved2;// 2B
unsigned long bfOffBits;// 4B
};
// sizeof(b)==14B - OK!
struct b
{
char nothing[14];
};
