Correct, your example works, BUT, if you modify it to act as my program
does, it crashes.
How to modify it then? Add an additional loop around the first one, like
this:
------8<------
...
while(1) {
for (i=4; i < n; i++) {
...
------8<------
If there is no bug, this should not be a problem, right? Well, there is one
:( ... This is the result I get:
------8<------

I'm using the latest CVS snapshot (updated today, 20/11 2002 22:00 CET)
Any input would be nice (and no, I can not/will not rewrite my program,
besides, this should be fixed no? ;))
