int i;

That code will work fine in debug mode but will most likely crash with the sortof error you have in release mode and the compiler won't pick the error.

WHY ... because variable global variable "i" was never set to any value

When you run in debug mode the compiler zeros all global variables there is a long story of why it does that but for now all you need to do is that it does.
 
So in debug mode testval will always come back with "0" because i is initialized by the debug mode to 0
 
In release mode it is highly likely this will crash as "i" could be any value including values which are way outside the array range of somearray.

See how the code above has the same problem as your code...
