If you're using Linux, run your test programs under valgrind. It'll help you immensely to find memory issues.

  I mostly use address sanitizer these days rather than valgrind. It's fast enough that you can just put it in your default compile flags for debugging.

    And it's available for Visual Studio, so you don't even need to be running Linux.

    Address sanitizers have bitten me before. Valgrind has not, aside from the times it wasn't supported on new macos. Just be careful.

    It is faster, but IME valgrind is more thorough. I have an option to run unit tests with valgrind.
