           Summary: Building CodeBlocks on Windows using mingw gcc 4.6.1
                    "-flto -fuse-linker-plugin" results in many linker
                    stage errors
           Product: gcc
           Version: 4.6.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: xunxun1982@gmail.com
              Host: i686-pc-mingw32
            Target: i686-pc-mingw32
             Build: i686-pc-mingw32


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++ --disable-bootstrap
--disable-werror --with-arch=i686 --with-tune=generic \
    --enable-languages=c,c++,fortran --enable-libgomp --enable-threads=win32
--enable-lto --with-system-zlib \
    --enable-libstdcxx-debug --enable-version-specific-runtime-libs
--enable-fully-dynamic-string \
    --disable-sjlj-exceptions --with-dwarf2 --disable-symvers
--enable-checking=release \
    --enable-plugins --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:

--------------------------------------------------------------------------------

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?
