--- Comment #32 from Nick Clifton <nickc at redhat dot com> --- Hi, I am wondering if there are two problems here, rather than just one. So please could you check a couple of things for me ? 1. Does iostream.exe fail to run if built without LTO ? 2. Where does iostream.exe fail ? Is it before main(), or when the libstdc++ library is being loaded, or somewhere else ? Thanks Nick -- You are receiving this mail because: You are on the CC list for the bug.
