If you have R&D Crash Program already in your tableau, is it legal to discard R&D Crash Program in order to develop another copy of R&D Crash Program?
No. At the point you *place* it (as opposed to after you pay for it), you already have another copy of it in your tableau, which is illegal.
(Building is a two-step process: placing it (simultaneously) and then paying for it. There's no "tentative" placement, see what's going on, then decide to not spend something, have that decision in turn invalidate your build, then "go back in time" and undo your placement. What you place you must be able to legally pay for and build.)
