--- Comment #29 from Joost VandeVondele <Joost.VandeVondele at mat dot ethz.ch> --- I've tried -fsanitize=leak and it works well, thanks! Concerning the speed, I'm still seeing about 20% slowdown (again, this is acceptable from my point of view). Under oprofile, the __sanitizer::internal_memset is near the top (see below), it this expected for -fsanitize=leak ?
