Because in the normal case for C/C++, folks don't use that many exceptions. So delaying doing anything until it's needed is a win. Obviously the normal case is different for Java. > We'd avoid a great many trips through > dl_iterate_phdr () and _Unwind_IteratePhdrCallback(). While I still like using dl_iterate_phdr instead of __register_frame_info_bases for totally aesthetic reasons, there have been changes made to the dl_iterate_phdr interface since the gcc support was written that would allow the dl_iterate_phdr results to be cached. r~
