In my project, the most frequent dynamic allocations came from std::vector in MinDistanceToLineSegment(...) and they can be avoided by using a boost::container::small_vector which allocates in the stack when there are fewer than N items. The sizeof items is only 32 bytes, so having 64 items in small_vector uses only 2KB in the stack.
