sanitize on in CMakeLists.txt

1. CMakeLists.txt set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -fsanitize=address") add_compile_options(-fsanitize=address) If a subdir is set with add_subdirectory and a module that does not support sanitize is imported from the path and needs to be removed, add -fno-sanitize=address to add_compile_options in CMakeLists.txt of the subdir to remove it. Basically, if you enable sanitize, sanitize will adjust ulimit's core to 0, so core will not occur. You can do this by putting the following part as an environment variable. (Below is the part you put in systemd's service) 2. service file in systemd [Service] LimitCORE=infinity Environment="ASAN_OPTIONS=handle_segv=0:handle_abort=1:abort_on_error=1:disable_coredump=0"
