 Even if the ast-optimizer is broken, 
 here is the bug report 
 
 Bison version  : unstable 1.75-1, this is the problem 
 but it i working with the stable 1.35-3.
 
 The file in question is
 http://gcc.gnu.org/cgi-bin/cvsweb.cgi/gcc/gcc/gengtype-yacc.y
 
 The error output got lost, I will retry it with the main branch was
 about this construction
 typedef_struct: ENT_TYPEDEF_STRUCT options '{' struct_fields '}' ID
 		   {
 		     new_structure ($1->u.s.tag, UNION_P ($1), &lexer_line,
 				    $4, $2);
 		     do_typedef ($6, $1, &lexer_line);
 		     lexer_toplevel_done = 1;
 		   }
 		 ';'
 		   {}
 		| ENT_STRUCT options '{' struct_fields '}'
 		   {
 		     new_structure ($1->u.s.tag, UNION_P ($1), &lexer_line,
 				    $4, $2);
 		     lexer_toplevel_done = 1;
 		   }
 		 ';'
 		   {}
 		;
 
 
 there was some conflict between the two.
 I am just compiling the new bison locally to avoid de-installing 1.35,
 and will report the exact bug tonight (Timezone: GMT +1 )
 
 I will also be looking into doing the switch over to the tree simplied
 version. it looks interesting.
