For-loop problem

[paolopiace]

I'm getting seg-fault in a for-loop like this, where I need to change the starting point within the body.

Is that accepted/allowed?

I'm using gcc version 4.4.3

Thanks!

for (s=N; s>= 0; s--) {

        { some code here }

        if (condition)
                --N;

        // NOTE: it's *never* N < s
}

Segfaults happen when you use invalid pointers. If your code has a problem, it's in the "some code here" part. Note though that s=N happens only once before the loop starts. Any changes to N afterwards has no effect on s.

Use the debugger. Step through the code one line at a time. Look at the values of variables as you step. Nobody here is going to be able to help much unless you post something that is more complete.
