> We tested the possibility of using geolocation during a hackathon we had in October with my team and we found some issues that caused core dumps.
> The problem lies with the usage of the `ast_geoloc_datastore_add_eprofile` function. In two places, the code tests that the return code of this function is not equal to zero. If it is not equal to zero, it frees the datastore and sets the pointer to NULL.
> However, this function does not return 0 when there is no error. It returns the size of the datastore.
