Hi Ole, What exactly is dotProduct? Is it a C++ function? If so, it will just get evaluated and the AST will contain the result of the evaluation. In that case I would expect it to only get evaluated once. How are you checking that it gets called multiple times? You might try setting a breakpoint in dotProduct and check where it gets called from.
