使用AddressSanitizer内存检测

修改cmakelist.txt，在project(xxxx)后面追加：

option(MEM_CHECK "memory check with AddressSanitizer" OFF)
if(MEM_CHECK)
    set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fsanitize=address")
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fsanitize=address")
    message(STATUS "Build with memory check")
endif()

编译追加cmake参数-DMEM_CHECK=ON：

cmake -DMEM_CHECK=ON

执行程序：

ASAN_OPTIONS=detect_leaks=1 ASAN_OPTIONS=detect_container_overflow=0 ./xxxx

发现问题时，程序会停下来并在终端报告问题，
