That's how C++ classes work. If you declare a variable inside a method that variable gets declared every time the method is called. If you want the variable to keep state between method calls you need to declare it as a member of the class inside the class declaration.

For more information see any tutorial on C++ classes and look for variable scope.

Any c++ block which created by gr_modtool has this feature.
c++ block run with for(int i loop. This "i" becomes 0 after every 8191
samples. When we put noutput_items=1000. "i" becomes 0 after  every 1000
samples, otherwise it becomes 8191 and return to 0
