--- Comment #16 from Jakub Jelinek <jakub at gcc dot gnu.org> 2011-03-07 20:41:12 UTC --- Created attachment 23576 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=23576 hack The c_parser_binary_expression stack impact could be decreased, either through a hack like this (forcefully split the function, so that when calling the first cast expression it will use smaller amount of stack, unfortunately the call isn't then tail callable and thus for an actual binary expression needs more stack), or stack/sp perhaps could be handled separately (global stack vector).
