Memory Corruption
After adding the following 2 lines in CMakeLists.txt: SET(CMAKE_CXX_COMPILER "clang++") SET (CMAKE_CXX_FLAGS_DEBUG "-O0 -g -fstack-check -fstack-protector-strong -finstrument-functions -fsanitize=address -fsanitize=leak -fsanitize=undefined -fno-omit-frame-pointer -static-libsan")
and building and running executable, I get the following segmentation fault. This also happens in other examples as well. These errors are not detected without adding the above lines.
