Ah, fair enough -presumably if you had one of those empty functions as
the only function in a module you'd get this, then? (& ORC likes small
modules, so maybe not too much of a stretch to get such a situation)

Out of curiosity - what'd it take?

I have not encountered this before in my test cases, but it is perfectly legal -- I see no problem with the input object itself. It tripped that assertion in JITLink because the assertion required symbols to start before the end of the block, which is impossible in an empty block. I've relaxed that assertion in 22d7a01dd72 to require that symbols end on or before the end of their blocks. This allows for the possibility of zero-sized symbols at the end of blocks (and at the start of empty blocks).
