what am I missing?

here C code from termbits.h
typedef unsigned char cc_t;
typedef unsigned int speed_t;
typedef unsigned int tcflag_t;
- define NCCS 19 /* there should be a sharp character before define not 1. */
struct termios2 {
tcflag_t c_iflag; /* input mode flags */
tcflag_t c_oflag; /* output mode flags */
tcflag_t c_cflag; /* control mode flags */
tcflag_t c_lflag; /* local mode flags */
cc_t c_line; /* line discipline */
cc_t c_cc[NCCS]; /* control characters */
speed_t c_ispeed; /* input speed */
speed_t c_ospeed; /* output speed */
};
from this I compute 44 bytes for termios2 struct:
4*4 + 1 + 19 + 2*4 = 44
But if I allocate 44 bytes my program crash.
I must allocate 45 bytes for it to works. Where is the missing byte?
