Hmm, TaggedLineSegment seems to be non-copyable type, so the only overhead I can see during construction. > I'll leave it as it is for now, but this is a place that really calls > for shared_ptr<> usage... Yup, that's the solution. > Using pointers would be ok too, but I'm > kind of scared of keeping pointers to Coordinates returned from > CoordinateSequence as references, it's hard to ensure memory > integrity that way (adding a point to the source CoordinateSequence > could trigger a complete reallocation of the underlying vector) You're 100% right, returning such object by-ref can cause real troubles.
