Further investigation suggests I was probably on the wrong track. Not sure
where
to look next.
My theory is it's a LoadIC failure --- You get a reference error trying to
point
to `f` after declaring `var f = (...a) => a` or similar. So, somewhere,
something is not being stored that should be, and at some point that leads
to an
access general protection fault. The closest code to the generated assembly
looks like it lives in `GenerateFastArrayLoad`, to me.
