I have to strongly disagree with you.
Try the output of this Cython code
print sizeof(char[1<<30]) * 3
versus the output of this C code:
#include "stdio.h"
int main() {
printf("%u\n", sizeof(char[1<<30])*3);
}
For the first you get -1073741824 (clearly wrong), and for the second
3221225472. (Used a 32 bit box)
