annotate lwasm/output.c @ 500:733fd05ca2a8

Initialize temporary line structures properly Apparently, not initializing all elements of a struct can lead to random problems if something somewhere decides it should reference one of those uninitialized fields. Who knew. Set the temporary line_t structure to zeroes before passing it into anything when calculating the stuff for "object" output which should at least make things predictable. This seems to fix a crash reported by "strick" in Discord.
