From: "pinskia at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c/50171] False positive -Wuninitialized warning Date: Wed, 24 Aug 2011 03:12:00 -0000 [thread overview] Message-ID: <bug-50171-4-Cydx8sHdoY@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-50171-4@http.gcc.gnu.org/bugzilla/> http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50171 --- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> 2011-08-24 00:05:25 UTC --- int baz(char **, const char *); int quux(char *); int foo(const char *a) { char *b; int t1; { char *t; if (!baz(&t, a)) t1 = -1 b = t; t1 = 0; } if (!t1) return -1; return quux(b); } --- CUT --- After some more optimization: int foo(const char *a) { char *b; char *t; if (!baz(&t, a)) ; else return -1; return quux(b); } looks like a correct uninitialized warning to me after inlinining has happened. b is initialized when the return value (t1) is 0 and uninitialized otherwise.
