This is actually a different problem, some STL classes are provided with
different ABI versions by libstdc++  and one can select which to use
with the macro 

 _GLIBCXX_USE_CXX11_ABI 
  
Defining _GLIBCXX_USE_CXX11_ABI=0 should do the trick for now.

cf: 
https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html
