i even managed to get pd-gui to crash once again with the same patches open, without getting an OOPS this time.
after removing some stuff from the patches i got it working ok .. not sure really , but clearly it's because of the stuff that i've done.
i didn't use any external btw and it's a compilation from Miller's sources.
i sand this for sort of informative purpose; also to say that pd didn't crash on me by itself never yet!
