 This is not a bug because func's c is not a reference to a variable but 
 a variable that is copied.
 If you want a function that does not copy, then use a `&' and then the 
 destructor is not called twice, only once.
 
 Read a C++ book for more information about pass by value, not reference.
 
 Thanks,
