If you do a search with Google with: switch bug "missing break" Or: switch bug "fall through" Or: switch most common programming bugs You will see a ton of pages. Wikipedia says this is a common bug: http://en.wikipedia.org/wiki/Switch_statement A bug in Python: http://bugs.python.org/issue4772 Gcj: http://gcc.gnu.org/ml/java/2001-12/msg00153.html Page on C++ pitfalls: http://www.gauravcreations.com/tutorials/c_pitfalls.html It's error 825 on Gimpel: http://www.gimpel.com/html/pub90/msg.txt Ona page of common C bugs: http://drpaulcarter.com/cs/common-c-errors.php#2.1 Another in Gcc: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31137 More: http://pear.php.net/bugs/bug.php?id=5020 http://sourceware.org/ml/gdb-patches/2006-04/msg00234.html https://savannah.cern.ch/bugs/?15576 http://aspn.activestate.com/ASPN/Mail/Message/php-Dev/901756 http://opensource.atlassian.com/projects/hibernate/browse/HHH-448 A page that warns again them: http://www.jaggersoft.com/pubs/CVu09_1.html Listed by Linus: http://lkml.org/lkml/2005/9/30/219 Java findbugs is supposed to find them: http://osdir.com/ml/java.findbugs.general/2005-01/msg00020.html In boost: http://www.boost.org/doc/tools/jam/jam/history.html If you keep searching you can find a good amount of them. It's not the most common kind of bug, but it seems common enough to deserve warnings, lints, several pages of "C/C++ traps & tricks", etc. There is also a well know bug by AT&T, but it's a little different: http://www.gowrikumar.com/blog/2009/01/06/att-break-bug/ Bye, bearophile
