This is very sick side case of updating prev_try pointer in duplicate_eh_edges. I think it is clear that maintaining prev_try pointer just to slightly speed up the lookup in foreach_reachable_handler is highly impractical. Once the other bugfix to EH code is in the tree, I will test patch removing prev_try and replacing its use by find_prev_try. Honza -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39862
