The issues where mainly related to implicit casts of shared_ptr to bools (something like "dataValid = ( dataSet )"). I changed this to "dataValid = ( dataSet != NULL )". Although this is not the C++11 way (we should use nullptr), it keeps compatibility with c++98 for now, as we are not yet sure if everything is fine on OSX (Linux + Windows was tested by me.
