I used shared pointers to trick the python garbage collector.
(not sure if it works the way i want, memory leak, but close).

shared pointers are only available from c++11. so you'd need to use a
recent compiler (such as gcc>=5.8 or so?) or pass -std=c++11 to an older
gcc (maybe >=4.9?)

try
$ make CXXFLAGS=-std=c++11\ -O2
or
$ make CXX=g++\ -std=c++11

maybe
$ ./configure CXXFLAGS=-std=c++11
also does the trick.
