It's also hard to see what is happening in 'C'. When I execute
this:

#include <stdio.h>
#include <stdlib.h>

int main(int cnt, char *argv[], char *env[], char *aux[])
{
    printf("Aux 0 = %s\n", aux[0]);
//    printf("Aux 1 = %s\n", aux[1]);
}

There is no pointer to the aux table passed to main, you have to skip past
the environment.  Also, the aux table is an array of key/value pairs.

This shows that ld-linux.so, that got called first, didn't
preserve the vector.

It does.


Here's a simple program to show you your pages size ;-), Now I don't
know enough about the elfinfo size and such to make this a real program,
but it should at least prove a point!

#include <stdio.h>

int main(int argc, char **argv, char **env)
{
       int i;
       long *p;

       for (i=0; env[i]; i++);
       p = (long*)(&env[i+1]);
       for (i=0; i < 10; i++) {
               long type = *p++;
               if (type == 6)
                       printf("pagesz = 0x%lx (%ld)\n",*p,*p);
               p++;
       }

       return 0;
}

Well this just shows that the table is somewhere on the stack
after the environment.
