I can't reproduce this. Here it does:
read(0, "h", 1) = 1
setitimer(ITIMER_REAL, {it_interval={0, 0}, it_value={0, 0}}, NULL) = 0
ioctl(1, TIOCGWINSZ, {ws_row=24, ws_col=80, ws_xpixel=0, ws_ypixel=0}) = 0
write(1, "h", 1) = 1
fcntl64(0, F_SETFL, O_RDONLY|O_NONBLOCK) = 0
read(0, 0x809c580, 1) = -1 EAGAIN (Resource temporarily unavai
fcntl64(0, F_SETFL, O_RDONLY) = 0
rt_sigaction(SIGALRM, {0x8067940, [], SA_INTERRUPT}, NULL, 8) = 0
setitimer(ITIMER_REAL, {it_interval={0, 0}, it_value={1, 0}}, NULL) = 0
time(NULL) = 1144017301
fcntl64(0, F_SETFL, O_RDONLY|O_NONBLOCK) = 0
read(0, 0x809c580, 1) = -1 EAGAIN (Resource temporarily unavai
fcntl64(0, F_SETFL, O_RDONLY) = 0
ioctl(1, TIOCGWINSZ, {ws_row=24, ws_col=80, ws_xpixel=0, ws_ypixel=0}) = 0
fcntl64(0, F_SETFL, O_RDONLY|O_NONBLOCK) = 0
read(0, 0x809c580, 1) = -1 EAGAIN (Resource temporarily unavai
fcntl64(0, F_SETFL, O_RDONLY) = 0
time(NULL) = 1144017301
write(1, "\33[1;52H\33[7m3\r\n\33[2C", 18) = 18

Can you build it with debugging symbols and run it in gdb?
