Dear developers, I have got a problem about g++ compatibility. I want to compile a c++ program by g++5.4, which need to link a library compiled by g++4.8. I noticed the dual_abi <https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html> since g++5.1, so I set -D_GLIBCXX_USE_CXX11_ABI=0 in my CMakeLists.txt. The compilation is ok but I got segmentation fault when I run the program. To make it clear, the program works well when I downgrade my compiler to g++4.8. I wonder if there is any way we can link old library compiled by g++4.8 without downgrade high version g++ compiler (g++5.1 above) ? Any suggestions and response would be appreciated!. Thank you! izhiqiu chen
