I'm a bit confused, why is using 12 bytes if it's a char + 2 int's?
I think i'm not understanding something.

I've redone using sizeof(t_st) in all points and this is the output:

tigre@enigma collector $ gcc pro.c
tigre@enigma collector $ ./a.out
5 0 0 0 5 0 0 0 5 0 0 0

tigre@enigma collector $ gcc pro2.c
tigre@enigma collector $ ./a.out
5 fffffffa ffffffff ffffffbf 5 0 0 0 5 0 0 0
5 fffffffa ffffffff ffffffbf 5 0 0 0 5 0 0 0

It have changed a bit, but strange things continue happening in pro2.c
