Not necessarily that simple. It might be easier if C++ had
try/finally (like Python does), but it doesn’t.

Here’s a patch I submitted to the Blender project some years ago to
fix up their directory-scan code to gracefully recover from errors
without either memory leaks or double-frees. This code is in C. It’s
all a matter of structured programming.
