Damn, that's annoying, maybe it's fixed.  I'm doing a new build from the
branch now.

One thing I just noticed, if I build it '-O0', instead of -O2 or -O1, it
passes.

I normally configure with, don't know if it would make a difference:
../gcc/configure --with-cpu=strongarm --enable-languages=c,c++,objc,f77 \
  --prefix=/usr/local --enable-shared --enable-threads --without-cvs \
  armv4l-unknown-linux-gnu

I'm building again, I'll let you know in a couple of hours when it reaches
the spot again.
