Hah, I teach my students to use Valgrind, and I’ve been pronouncing it wrong this whole time. Guess I’ll have to make sure to get that right next semester :)

The magic of Valgrind really lies in its ability to detect errors without recompiling the code. Sure, there’s a performance hit, but sometimes all you have is a binary. It’s damn solid on Linux, and works even with the custom threading library we use for the course; shame the macOS port is barely maintained (last I checked, it only worked on OSes from a few years back - anything more recent will execute syscalls during process startup that Valgrind doesn’t handle).
