I do not understand what this output is telling us. Here is the demangling of the symbols referred to:
T1 * <unnamed>::emplace<lom::lb::CounterWrap<lom::lb::CounterCmp<unsigned int, std::greater<unsigned int>>>>(lom::byte_stream &)
T1 * <unnamed>::emplace<lom::lb::CounterWrap<lom::lb::CounterCmp<unsigned int, std::greater<unsigned int>>>>(lom::byte_stream &)
It appears that the unnamed classes are given random internal names (de4062607 and 2372d2807). If so, this is probably a harmless difference.
