No, each instance has its own symbol table. Thus instances can't make callsinto each other as they could before - and I think that's all to the good :)
More questions: what's the use case for loading multiple instances of a shared library into the same memory space? Can this be done on all supported platforms? Also, is there a fairly commonly used, extant example of a currently maintained library out there that supports multiple instantiation that you can point me to?
