> The {{pn_ptr_base::inspect()}} function in {{cpp/src/object.cpp}} calls {{pn_string(NULL)}}
on line 36 and never frees the allocated memory with {{pn_free()}}.
> The fix is to create the std::string as a temporary variable, then free the pn_string_t,
then return the temporary std::string, like this:
> {{std::string tmp(pn_string_get(s));}}
> {{pn_free(s);}}
> {{return tmp;}}
