Little demonstration:
> cat size_t.cpp
#include <iostream>

int main(void) {
  std::cout << (1 << ((sizeof(std::size_t) * 8) - 1)) << std::endl;
  std::cout << (((std::size_t) 1) << ((sizeof(std::size_t) * 8) - 1)) << std::endl;
}
> g++ -o size_t size_t.cpp
size_t.cpp: In function ‘int main()’:
size_t.cpp:4: warning: left shift count >= width of type
> ./size_t
0
