Hi, I have problem with pointer in function return. My code: using namespace boost::python; v8::Platform* InitializePlatform() { v8::Platform* platform = v8::platform::CreateDefaultPlatform(); return platform; } BOOST_PYTHON_MODULE(hello) { def("InitializePlatform", InitializePlatform, return_value_policy()); } Python code: import hello x = hello.InitializePlatform() Building is ok, but when i try call InitializePlatform i have error: Segmentation fault gdb: (gdb) run test.py Starting program: /usr/bin/python test.py [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
