This makes running 4.3 programs with the 4.4 libraries impossible,
as the library will receive garbage on its eigth argument.

Why? The first argument should tell how many arguments exists. set_options has: if (num >= 7) compile_options.bounds_check = options[6]; if (num >= 8) compile_options.range_check = options[7]; Thus if there is no 8th argument, there should be no problem (assuming that there are reasonable default values). -- burnus at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |burnus at gcc dot gnu dot | |org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37501 ^ permalink raw reply [flat|nested] 4+ messages in thread
