Sounds like one compiler is checking array bounds for you (with CVF this is /check:bounds) and the other isn't. Generally it is considered bad form to purposefully access array elements outside of the defined limit, but lots of old code does this. So you need to determine if you would like to take advantage of the runtime error and prevent this from happening, or just do a /check:nobounds in your project setup and CVF will happily ignore this like the other compiler, as long as you don't index yourself into memory protection problems.
