Yeah, I started trying out valgrind, which seems to give a decent 
report. It slows down the compiler a bit, but that's ok.

In any case, I realized that I need to write some more targeted tests, 
because the template I want to replace is used all over the place, so I 
would need to change them all in order to reduce memory usage.
