Looks like a heisenbug. Can't reproduce it when i use the preprocessed output created by -freport-bug, only when i try to normally compile the file. If the same happens in your end, you could try (with gcc 5.1.1): git clone https://github.com/ericniebler/range-v3.git cd range-v3 && mkdir build && cd build cmake .. && make alg.partial_sort_copy
