Not sure, i probably shouldn't answer if I'm not sure.. but maybe that's a default constructor that's part of a class? Haha, like I said.. I'm probably wrong.. but just an idea.
its a public function. so is it possible that, somewhere in the family tree that this class is derived from, there is a call to this function that i have not found? that has to be it right?
Somewhere in the main program, an object of the class is making a call to the member function. That would be my guess.. it's hard to tell without the code. it might be possible you have a member funtion call in a member function, though.
