• try gcc 7 or gcc 6.3.1
• ~try clang~

  clang -o bin/release/intmain  obj/release/src/CustomTests.o  obj/release/src/rideables/BonsaiTreeRange.o  obj/release/src/rideables/BonsaiTree.o obj/release/src/intmain.o -l:libjemalloc.so.2 -lparharness -lpthread -lhwloc -lm -lrt  -L ./ext/parharness -ftrapv -Wreturn-type -W -Wall -Wno-unused-variable -Wno-unused-but-set-variable -Wno-unused-parameter  
  /usr/bin/ld: obj/release/src/CustomTests.o: undefined reference to symbol '_ZTVN10__cxxabiv121__vmi_class_type_infoE@@CXXABI_1.3'
  /usr/bin/ld: /usr/lib/libstdc++.so.6: error adding symbols: DSO missing from command line
  clang-8: error: linker command failed with exit code 1 (use -v to see invocation)

solution: use gcc version < 8
