From: "mckelvey at maskull dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c++/40723] New: Optimizer Causes Undefined References Date: Sun, 12 Jul 2009 00:12:00 -0000 [thread overview] Message-ID: <bug-40723-6183@http.gcc.gnu.org/bugzilla/> (raw) Valid code that links fine without optimization gets undefined references at -O3. The references are to such as vtable, L8185, WinMain, etc. Full log attached. I await direction as to what to provide to help solve this. Temps will be fairly large, and I don't know how to approach a smaller test case. (Compile error in log has been separately reported.)
