I've configured GCC with following options:
../gcc-current/configure --prefix=/home/artem/testing/gcc46 --enable-shared
--enable-bootstrap --enable-languages=c,c++ --enable-threads=posix
--enable-checking=release --with-system-zlib --disable-libunwind-exceptions
--enable-__cxa_atexit --enable-libssp --with-gnu-ld --with-lto --disable-nls
--verbose --with-arch=athlon64 --target=x86_64-slackware-linux
--build=x86_64-slackware-linux --host=x86_64-slackware-linux --disable-multilib
--enable-checking=all
The build fails with this error:

If --enable-checking=release is used instead of =all, then the build
completes successfully.
