It's running on a RD-6281-A. -bash-3.2$ uname -a Linux feroceon 2.6.22.18 #1 Tue Dec 23 17:32:37 EST 2008 armv5tejl GNU/Linux The binutils version that I am currently using is: -bash-3.2$ as --version GNU assembler (GNU Binutils) 2.19.51.20090522 I use the following to build binutils: #! /bin/sh export CC=gcc export CXX=g++ unset CFLAGS unset CXXFLAGS unset LDFLAGS unset FFLAGS export CPPFLAGS="-I/home/dave/opt/gnu/include -D_LARGEFILE64_SOURCE" export PATH=/home/dave/opt/gnu/gcc/gcc-4.3.3/bin:/home/dave/opt/gnu/bin:/home/dave/opt/perl/bin:/bin:/usr/bin date ../src/configure --prefix=/home/dave/opt/gnu --disable-nls && make && make -k check date My bootstrap compiler is: -bash-3.2$ gcc -v Using built-in specs.

I believe this is the long branch stub problem. You may be able to work around it by adding --disable-stage1-checking to your GCC configure options. Another work around is to use binutils with the tag D2009.05.22.11.00.00 UTC. This is just before the change that breaks binutils for me. I'm building for arm.
