Hi Dave,
Yep. This is JITLink specific, so we could only have observed it on MachO
x86-64 or arm64 until recently. It takes a little bit of poking to get IR
to produce a zero-lengh section on MachO, but not much.
Jared Wyles recently contributed an initial JITLink ELF implementation, so
the fix seems timely -- we might have been about to see more of it.
-- Lang.
