Okay, friends. I have a challenge. Who can make the sneakiest memory leak example? I need to stump a class of students with something only valgrind can find and I'm having a hard time.

Well, language? Any special framework in use? Working with pictures is a good one most of the time. Calling some unmanaged code and forgetting to free the memory buffer.
Big pictures will sink the ship after a few iterations. Depending on what and how of course

This. Still unsolved 🙄

Best thing would be to use a nested struct and do some #pragma pack padding with pointer arithmetic

Ask valgrind them

do something iteratively and leak a single byte every loop from a called function called by a function called by the loop?
