Try first compiling with the command-line parameters

  -fsanitize=address -D_GLIBCXX_DEBUG

This is easier because you don't need to learn new things. When you run
the program if the checking code added by those options detects a problem
it will tell where it's happening.

(The advantage of using valgrind is that it will detect even more runtime
errors.)
