* [Bug c++/40723] New: Optimizer Causes Undefined References @ 2009-07-12 0:12 mckelvey at maskull dot com 2009-07-12 0:14 ` [Bug c++/40723] " mckelvey at maskull dot com ` (3 more replies) 0 siblings, 4 replies; 5+ messages in thread From: mckelvey at maskull dot com @ 2009-07-12 0:12 UTC (permalink / raw) To: gcc-bugs 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.)
