An ancient (at least 33 years old) stack-overflow bug has been discovered and fixed in yacc, thanks to a new malloc() implementation by Otto Moerbeek. More info and a complete description of the bug can be found here.

"Edit: It seems that yacc is not technicly a part of OpenBSD so I guess that's why it wasn't discovered sooner."
It wasn't discovered sooner because it was obscure, not because it wasn't a part of OpenBSD. The new malloc implementation made the broken code fail reliably so it could be tracked down and fixed.
Please, read articles before you comment on them ;^)
