--- Comment #3 from Marc Glisse <glisse at gcc dot gnu.org> ---
gcc 4.6 and 4.8 branches are old and not supported anymore. Besides, trying
4.6.0  (with unidentified patches!) instead of 4.6.N with the largest possible
N is just asking for trouble (the problem may already be fixed in 4.6.N).
Google also has plenty of hits for your error, some may be relevant.
