I see another bootstrap failure with a compiler configured for
i486-linux-gnu.

configure --enable-languages=c,c++,java,fortran,objc,obj-c++,ada,treelang --prefix=/usr/lib/gcc-snapshot --enable-shared --with-system-zlib  --disable-nls --enable-__cxa_atexit --enable-clocale=gnu --enable-libstdcxx-debug --enable-java-maintainer-mode --enable-java-awt=gtk --enable-gtk-cairo --enable-plugin --with-java-home=/usr/lib/gcc-snapshot/jre --with-ecj-jar=/usr/share/java/ecj.jar --enable-mpfr --disable-werror --build=i486-linux-gnu --host=i486-linux-gnu --target=i486-linux-gnu

Building with -j3, I additionally see:
