--- Comment #3 from Paolo Carlini <paolo.carlini at oracle dot com> ---
Can you please try to reduce your testcase to a manageable size? Normally, for
proper C++ front-end issues less 50 lines are enough and no special command
line options are needed, but your *.i has a lot of target-specific code. We
have a wiki entry: http://gcc.gnu.org/wiki/A_guide_to_testcase_reduction

Thanks!
