I can't reliably reproduce it. I took moreblock:iron_stone_bricks into the replacer with shift+rightclick, then either right- or leftclicked a slab or sign. Sometimes it works. When I blink it does not :D
Maybe the same as #2 , maybe not.

This is the same crash as #2. I did manage to create another similar crash, but this isn't the right stacktrace. The other crash has already been fixed too.
