Jason -- Would you mind looking at PR 8461 (stabilize_throw_expr), PR 8674 (cp_expr_size), and PR 8625 (cp_convert_parm_for_inlining)? You've been in that code most recently, so you might be able to make headway more quickly than anyone else. Thanks, -- Mark Mitchell mark@codesourcery.com CodeSourcery, LLC http://www.codesourcery.com
