Like I said before the return address can be anything. It could for instance point to some instruction in a random function and then the stack unwinder will think thread_start was called from that function. There's no check you can add to libgcc to distinguish that from a normal valid return address. _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
