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

...which doesn't change at all while the loop is running.

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):

 | tomas frau-mahlzahn:~$ cat fo.c
 | #include <stdio.h>
 | 
 | int main ()
 | {
 |   int i;
 |   while (i < 25000)
 |   printf ("%d\n", i);
 | }
 | tomas frau-mahlzahn:~$ 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
