OK. I just tested with gcc-4.9 and the ICE is gone but there is still a problem
with the build
So the end of the build log looks like:

Running that offending command with gcc-4.9 and 4.8 shows:
gcc-4.9 builds OK:

So what I don't understand is why the build is falling over as running the
command onit's own seems to be OK?
I did this build as
CC=gcc-4.9 dpkg-buildpackage -B -uc -us
which appears to change gcc to gcc-4.9 everywhere it needs to.
