I found that if I add the option "-flto-partition=none", the problem will disappear.

Hi, all My gcc4.6.1 configure with : ./configure --prefix=/mingw --host=i686-pc-mingw32 --build=i686-pc-mingw32 --target=i686-pc-mingw32 \ --with-lto-plugin --with-host-libstdcxx=-lstdc++

--enable-cloog-backend=isl --enable-static --disable-shared \ --disable-nls --disable-win32-registry My ld version is : 2.21.52.20110708 When I build Code::Blocks, if I add "-flto" to the compiler option, and add "-Wl,-O1 -Wl,--sort-common -Wl,--as-needed -s -flto -fuse-linker-plugin" to the linker option, that will result in many linker stage errors:

undefined reference to `_imp___ZTV17wxStringTokenizer.local.832' -------------------------------------------------------------------------------- But either .objs\sdk\wxpropgrid\src\*.o or libwxmsw28u.a don't have any symbols like "*****.local.****", the libwxmsw28u.a only have the symbols like "_imp___ZTV17wxStringTokenizer". I don't know how the "*****.local.****" symbols come out? It's a gcc lto plugin bug or ld bug? I remove "-Wl,-O1 -Wl,--sort-common -Wl,--as-needed", and it also has the problem. ps: other linker option like "-Wl,--enable-auto-image-base -Wl,--add-stdcall-alias -Wl,--enable-auto-import" is Code::Blocks's default option. see gcc bugzilla: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49844 -- Best Regards, PcX
