I would almost certainly say that your problem is pointer based.

The reason it works for a set of variables decalred in one order and not
in another is due to how the order of the variables affects program
copilation.

Lets take you case where things work OK and lets assume that you have a
pointer problem. What is probably happening is your code follows the bad
pointer but ends up in a bit of memory that (luckily) does not cause the
program to crash or may even produce semi reasonable results.

When yopu com[pile the program with the variables ordered the bad way
the copde follows the pointer as per before but ends up in a memory
address that contains differnt data (as the location of the variables
have been set to different places) that is not compaitble with wjhat the
pointer is being used for and alas your program goes awol.

This sought of thing is also responsible with code that breaks upon the
inclusin of a comment???? This may slightly change the compiled programs
structure and cause a pad pointer to land in a really bad data segment
and crash.

Anway hope this helps. I would be tracking your pointers and see where
they are going.

I could also be wrong but I have seen this sought of thing many toimes
before and the problem is usaually a bad pointer.

Goodluck
