--- Comment #3 from David Binderman <dcb314 at hotmail dot com> ---
This configure line seems to work:

../trunk/configure --prefix=/home/dcb/gcc/results.262304.ubsan \
        --with-build-config=bootstrap-ubsan \
        --disable-multilib \
        --disable-werror \
        --enable-checking=df,extra,fold \
        --enable-languages=fortran

So it's looking like the rtl or yes flags are the problem.
