I love valgrind and it saved my ass countless time when tracking memory leaks or overflows. The main issue I've always had with it is filtering the output easily. When you use external libraries (portaudio or Qt for example but also proprietary libraries I had to use at work) a lot of the debug messages pollute what is really yours and your leak is then a needle in a haystack.

You know about suppressions, right? Particularly the --gen-suppressions option? See http://valgrind.org/docs/manual/manual-core.html#manual-core... and http://valgrind.org/docs/manual/mc-manual.html#mc-manual.sup....

I remember trying multiple solutions with exception files and such but not having a lot of luck at filtering the ones I did not care about while keeping my own errors displayed. It's clearly user error on my end but I always gave up and rewrote smaller samples without external dependency when I could.
