All those people running yacc parsers under valgrind memcheck or Purify probably just thought "Oh, it's yacc, how could yacc still have bugs after 30 years? I'll just add a suppression rule..." :)

They also found a nearly-25-year-old bug in SAMBA a few months back. http://undeadly.org/cgi?action=article&sid=2008050819325...

that bug was in our libc, not samba. samba just had some code to work around the problematic behavior.
