--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> 2011-08-24 21:33:23 UTC --- (In reply to comment #0) > Created attachment 25070 [details] > Patch for c-parser.c > > Error message: > > ../../gcc-4.7/gcc/c-parser.c: In function 'c_expr > c_parser_postfix_expression_after_primary(c_parser*, location_t, c_expr)': > ../../gcc-4.7/gcc/c-parser.c:6664:16: error: 'origtypes' may be used > uninitialized in this function [-Werror=maybe-uninitialized] This patch is correct and does prevent the warning as we are using an uninitialized value of origtypes (though if we inline build_function_call_vec and then convert_arguments, the only time it is used unitialized is when exprlist is non NULL but that requires a lot of optimizations to happen really and it might only be seen by the human eye rather the compiler).
