Current implementation of ggc_alloc_rtvec_resized allocates more spaces for rtvec. This patch uses original formula to compute size for rtvec. Bootstrap on x86_64 successfully.
OK for trunk? By the way, I don't have write access to SVN repository yet. Could you please help commit it after approval?
