Alexander, also remeber if you create objects in your dynmaicly loaded library
you must free them using function from that library (delete and new can be 
overloaded). I.e. library should provide functions:

Foo* foo_new (...);
void foo_delete(Foo*);

for each class it returns objects of to the main program.
