Really?
$ cat test.c
#include <stdio.h>
int main(void)
{
printf("sizeof(int) = %i\n", sizeof(int));
printf("sizeof(long) = %i\n", sizeof(long));
printf("sizeof(size_t) = %i\n", sizeof(size_t));
return 0;
}
$ gcc -otest test.c
$ ./test
sizeof(int) = 4
sizeof(long) = 8
sizeof(size_t) = 8
Hm, it does not seem that sizeof(size_t) == sizeof(int).
$ uname -m
x86_64
Yes, this is a 64-bit system.
Anyway, comparing it with -1 is ALWAYS OK in spite of this!
$ cat test2.c
#include <stdio.h>
int main(void)
{
size_t x = 0;
--x;
printf("x = 0x%lx\n", x);
printf("(x == -1) = %i\n", (x == -1));
return 0;
}
$ gcc -otest2 test2.c
$ ./test2
x = 0xffffffffffffffff
(x == -1) = 1
So at least with gcc that comparison is OK anyway. There has to be something
else that causes that problem.
