From: "jakub at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/54020] [c++0x] incorrectly accepted constexpr functions Date: Thu, 19 Jul 2012 06:40:00 -0000 [thread overview] Message-ID: <bug-54020-4-3Xi1i5wj1I@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-54020-4@http.gcc.gnu.org/bugzilla/> http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54020 Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-07-19 06:40:41 UTC --- ... the program is ill-formed; no diagnostic required. ^^^^^^^^^^^^^^^^^^^^^^^ GCC doesn't immediately see that the first operand of ?: is zero or non-zero in that function, so assumes it could be either zero or non-zero and doesn't diagnose, you get diagnostics only when you are actually using the function in some constexpr var initializer or other context where a constant expression is required.
