i is uninitialized here. It contains a random value...

So I don't understand why this program terminates at all (it should
terminate either *immediately* or *never at all*.

Even 30 seconds seem too long (or too short, depending on the initial
value of i).
BTW, if you compile that with -Wall, the compiler would have told you
that (needs option -O as well):
| [EMAIL PROTECTED]:~$ cat fo.c
| #include <stdio.h>
|
| int main ()
| {
| int i;
| while (i < 25000)
| printf ("%d\n", i);
| }
| [EMAIL PROTECTED]:~$ gcc -O -Wall -o fo fo.c
| fo.c: In function 'main':
| fo.c:7: warning: 'i' is used uninitialized in this function
| fo.c:8: warning: control reaches end of non-void function
