GCC 3.3 and GCC 3.4 trigger code generation bugs in earlier versions of
the GNU compiler (especially GCC 3.0.x versions), which lead to the
miscompilation of the stage1 compiler and the subsequent failure of the
bootstrap process. A workaround is to use GCC 3.2.3 as an intermediary
stage, i.e. to bootstrap that compiler with the base compiler and then
use it to bootstrap the final compiler.
