An even shorter example is the following: -----------------snip here---------------- void foo(int i) { switch(i) { case 0: break; case 1: break; } } -----------------snip here---------------- Compiling this with gcc 3.2.1 or mainline I get the message PR8828.c: In function `foo': PR8828.c:7: warning: will never be executed PR8828.c:5: warning: will never be executed i.e. the compiler complains about the "break" statements. This is a regression from gcc 3.0.4 where the warning is not issued. http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=8828
